oops, at the link then:
_______________________
"I wasn't sure whether to post this here or in the MAME section or in the Arcade - General section so if it's in the wrong section then feel free to move it.
I recently bought a Sega Hang-On board set from one of Gamingheaven's eBay auctions. It wasn't actually a full board set, just the CPU board and control board (no rom board (sprites) or sound board (Z80 + samples)).
It arrived a couple of weeks ago and I plugged it in to my Out Run cab just to see if it would power up and display anything as the listing did say that it was working, albeit with a fault. To my surprise it powered up fine and displayed everything except the sprites and obviously there was no sounds. But everything else was there, the road layer, the text layer, the 2 tile layers, all good. The intro sequence played, it went into attract and then the high score table scrolled up the screen at the end of attract.
So I unplugged it and packed it back up again and today decided to pull it out and dump the EPROMs to compare them with the known good sets in MAME (hangon and hangon1). Because I've only got the CPU and control boards it means I've only got the EPROMs for the main cpu (ic22, ic8, ic20 and ic6), the sub cpu (ic63 and ic51), the road (ic108), the tiles (ic38, ic23 and ic7) and the sprite zoom table (ic123).
After cleaning up the legs of all the EPROMs with a fibreglass pencil I dumped them all multiple times and confirmed that each dump was good by comparing in a hex editor. The SHA1/CRC checks for the road, the tiles and sprite zoom table EPROMs all agreed with the roms in the hangon/hangon1 sets but the main cpu and sub cpu checksums were all different.
So I loaded the game up MAME (it complained that the checksums were wrong but happily played the game) and immediately went into the service menu to do a memory test. Memory test showed good for all 6 main cpu/sub cpu EPROMs so this gave me confidence that my dumps were indeed good.
So I started a game with the easiest time settings via the dip switches and the first thing I noted was that you started a game with 90 seconds on the clock as opposed to the 75 seconds that you start a game with in the hangon/hangon1 sets on the easiest dip switch settings.
It then didn't take long to notice that the track layout is radically different to that of the hangon/hangon1 sets (actually the hangon/hangon1 sets have an identical track layout as all the track data is stored in the sub-cpu program and the sub-cpu program in those sets is identical).
The first stage is considerably easier on my undumped set than the hangon/hangon1 sets, there are less bends and the enemy bikes seem more docile and less inclined to try and ram you off the road!
Even though you start the game with more seconds (90/85/80/75 for normal/medium/hard/hardest on my un-dumped set versus 75/70/65/60 for hangon/hangon1) when you hit the first checkpoint you only get 55 seconds extra on the clock as opposed to 60 seconds extra when you hit the first checkpoint on hangon/hangon1.
I played through a bit further and I'm pretty sure that the rest of the stages are different too (although it's difficult to compare in your mind when you're switching back and forth between rom sets and then playing through the game!). The best way to compare I guess would be to record footage of both games and then play them back side-by-side.
The ending sequence is identical in both mine and the hangon/hangon1 sets.
Now because I only have the CPU and control boards it's impossible to know if the sprites that would have been on the sprite board EPROMs and the sound samples/Z80 code that would have been on the sound board are identical to those of the hangon/hangon1 sets but being as though the road/tiles/sprite zoom table all match then I'd go out on a limb and say the other EPROMs would probably also have matched and it's only the main cpu/sub cpu EPROMs that differ. As the chances of mating my board set up with its original sprite board/sound board are virtually nil then I guess we'll never really know the answer (unless someone else, somewhere in the world, has got an original 4-board set with the main cpu/sub cpu code the same as mine!).
So at this point I'm thinking that I might have an early version of Hang-On and started examining the boards closer. The sub cpu EPROMs are labelled with the original Sega labels but are numbered differently than the ones from the hangon/hangon1 set. Mine are labelled epr-6838 and epr-6839 whereas the hangon/hangon1 EPROMs are labelled epr-6919 and epr-6920.
Unfortunately the original labels are no longer on the main cpu EPROMs, they've been removed at some point in their life and replaced with black sticky tape. The board itself has been repaired at some point (looks like 15/8/1995 from the repair sticker) so it's impossible to say whether the original EPROMs were removed and replaced at that time or whether just the labels were removed and black tape stuck on or what! But the fact that these roms all show good in the memory test of the service menu makes me believe this is genuine Sega code.
There are lots of patch wires going all over the board, impossible to say whether this is as a result of the repair of whether it left the factory like this.
I examined the date codes on most of the chips and the latest I observed was 8519 so that puts that chip at somewhere in mid May 85. There is what looks like a date stamp at the bottom of the CPU board saying 850626. I know that Hang-On came out in '85 but I don't know when the first units arrived in the hands of arcade operators.
Anyway, I've taken a few (quite a lot actually!) blurry shots with my phone so that you can see the extent of the patch wires all over the board!

And here's some footage of the EPROMs running in MAME :-
http://www.youtube.com/watch?v=r5L8Hl8NVEc
Sorry for the dodgy camera work but it's not easy trying to play the game whilst holding a phone to record it at the same time!
And finally here's the actual board set running in my Out Run cab :-
http://www.youtube.com/watch?v=dKCxJeqno7w
I'd like to share the EPROMs with the rest of you but I'm unsure of the legality of sharing what it in effect copyrighted material. If someone tells me that it's OK to do so then I'll upload them to my webspace. I can't imagine Sega would be too annoyed with me for sharing 28 year old roms but I don't want to tempt fate.
It would be nice if these could be added to MAME as a third hangon set but I don't know whether they'd take them as they're not a full set of roms (obviously missing the sounds and sprites)."

The answer to that should be yes.....especially when he provides actual proof [and appears to have done so]. If it doesn't get added, then at least it should be documented to show an earlier version does exist in case that version needs to be added to the search list. The cab owner should look at this as helping other cab owners preserve the game in case others have same pcb version.

I'm not reading all of that but the procedure is dump the roms and put them in a folder then with the latest mame.exe run:
mame -romident foldername
If any give a no match email them in.

Hi
I just registered on here as I'm the one who has dumped these Hang-On roms and I'm unsure what to do next as regards submitting them to the Mame development team.
I did as you suggested and ran mame64 -romident hangon with my freshly dumped main cpu and sub cpu roms in the hangon folder and it just said "Identifying hangon...." and nothing else so I'm not sure whether the romident function in mame64 for Mac OS X is working as it should do!
I honestly believe these roms to be currently undumped and would love to share them with the rest of the Mame community. The track layout on my version is completely different from the hangon/hangon1 sets. Also, the time you start a race with and the time you get for reaching checkpoints differs from the hangon/hangon1 sets too. The roms all show as "GOOD" when the memory test in the service menu is selected.
Is there somebody that I could email the 6 roms to in order that they can do some further checks on them?
Many thanks
Ade

That PCB is annoying as hell to work on. There is a reason my hang-on has been in pieces for the last 4 years.
Thanks for listening.

Thanks for doing this. It should also help other pcb owners/cab owners in case any of the roms on the pcb go sour over time and need to be replaced with a specific version set.

I think this un-dumped Sega Hang-On is the Ride-On version.
It's not a hacked version as far as I can tell you I'm sure of it.
This video shows the 1st stage just like the footage running in MAME from grog:
http://www.youtube.com/watch?v=Zhk35PQMzS4
This video shows a bit of the 1st stage like 20 seconds:
http://www.youtube.com/watch?v=SjcMMysPWwQ
Now all we need is the Sega Hang-On Ride-On manual and even the schematics, so if there's anyone who is seeing this message could you please upload all the pages from manual and schematics so we can find the evidence that we need for this version of Sega Hang-On.
If there's anyone who has a Hang-On (ride-on) pcb with the labels on ic 6, ic 8, ic 20, and ic 22 that shows epr- numbers and even letters on it could you take photos and upload them please so we can have label proof. It has to have a REV A sticker like this one for example: http://homepage.ntlworld.com/cmonkey/IMAG0527.jpg.

I don't know if the Hang On manual covers all different model types, but if not, there might be another way of determining the model type. ArcArc does have a page scan of the dip switch settings online that covers the "ride on" model.....assuming that the ride on model has different setting options compared to upright or sit-down models of Hang On.

Did a full play, and there are two extra foot pedals. They aids you in taking turns with a far greater grip than normal.
Now, how many versions could have "foot pedals" in them? :P

Something I never noticed, not sure if all the sit downs had them....
http://www.arcade-museum.com/game_detail.php?game_id=8068
"The sit-down version lets you steer your bike by moving your weight left and right, but there are neither force feedback or mechanics in it. However, when making a turn, you can push down on the foot peg to make the bike turn faster."

What do you think?
According to the upright and the Japanese sitdown manual the FOOT SW R & FOOT SW L on page 15 on upright and page 14 on Japanese sitdown it says:
Applicable only for the
RIDE ON type
(not the UPRIGHT/SITDOWN type)
I have the Mini Upright Hang-On Manual (2nd PRINTING-JN | MANUAL NO.420-5278 Rev) in English and the roms are from Hang-On (Rev A). Also the shipping settings are the very same on page 7 like the ones on page 8 on upright and page 10 on Japanese sitdown.

I agree with 'super', this is now definitely looking like my CPU/control board (and hence these roms) came from the ride-on version. I hadn't looked through the service menu completely before but now that I go into the INPUT TEST I see there's two extra settings for FOOT SW.R and FOOT SW.L. These settings are not in the hangon/hangon1 sets.
I've PM'ed a member on the J+ forums who may have a ride-on version, if he has and can photograph the board set for us, then it may well prove conclusive. He may also be able to dump the remaining missing roms from the sprite board and sound board to make this a full set.
This may also explain why my boardset has got an oily/greasy residue over certain part of it, maybe the oil/grease came from the hydraulics of the moving bike cabinet.

The 68k code for the INPUT TEST section of the service menu for these roms is at $487c-$494d in the main cpu program.
In particular FOOTSW.R and FOOTSW.L are bits 6 and 7 respectively of the word at $e01000.l
It should be trivial to alter the segahang.c driver to add support for these two switches.

Did it use hydraulics for centering? I assumed it was pneumatic or sprung.
The residue could have come from someone oiling the joints, or it might have been an attempt at water proofing it.

Actually I think you're right smf, I think ride-on just used a big spring for centering, the residue is probably from someone lubricating that, like you said.
After seeing the scan of the ride-on time difficulty settings it throws a spanner in the works as those settings show that on the easiest time difficulty dip switch setting you start stage 1 with 75 seconds. However on the roms that I've dumped you start easy setting with 90 seconds on the clock. So either the manual is wrong (which it could well be as it shows that you start stage 1 on HARD skill level with 80 seconds which is more than the easy and medium difficulty settings, surely the amount you start with should go DOWN as the difficulty gets harder, not up!) or something else is going on here.
But then the youtube video that 'super' posted of the guy trying to play the broken ride-on shows that he started the race with 80 seconds on the clock (it's impossible to see the countdown time when the race starts but you can time a real game of Hang-On in MAME against the video until such point where you can see the actual timer on the screen on the video and then work backwards from that to the amount that would have been on the clock at the start of the game). My roms give you 80 seconds on the clock if the time difficulty is set to hard (just like the manual scan shows for the hard setting). He never makes it to a checkpoint due to the throttle cable being busted so it's not possible to see how much extra time he would have gotten had he done so.
Anyway, I've had a reply from the guy on the J+ forums and we're in luck! He does have a ride-on Hang-On and he's kindly going to take some pics of his boards so that might prove conclusive as to whether these roms have come out of a ride-on Hang-On or not. He hasn't said yet whether he has the ability to be able to dump the roms.
I'll keep you informed when I know more.

Although it's a little difficult to tell for sure from the dip switch settings pdf that you've linked to it does indeed look like the time settings for the first stage of the race are 90/85/80/75 (easy/medium/hard/hardest) which are the same for the roms from my board.
The guy on the J+ forums has posted some pics of his boards. I'll copy them to here for people who can't access the tech section of those forums.
 
His sub-cpu roms are labelled the same as mine. My main cpu eproms have had their original labels removed unfortunately so it's impossible for me to tell whether mine were labelled the same as his but the labels on his are different to the ones from the hangon/hangon1 sets.
He doesn't have access to an eprom dumper at the moment (he may do when he returns to work next week, time dependent).
He's said that there's a possibility that this board set is a mixed up set as it's his spare set so he's going to photograph the actual board set that's inside his ride-on machine for us soon. Hopefully it's a confirmed original board set that's in his ride-on.

Here's a video showing you the ride-on version of Hang-On at 0:43:07 to 0:49:54 (spoiler alert!):
http://www.youtube.com/watch?v=kkC9YoDvVC0
It also shows After Burner II (spoiler alert!), Space Harrier (spoiler alert!), Out Run overseas version (spoiler alert!), Super Hang-On mini ride-on version (spoiler alert on Beginning - Africa), Enduro Racer YM2151 version (Although the quality may not be good at the end), and Super League (Although the quality may not be good sometimes).

I have a functioning upright and a disassembled sit on Hang-on cabinets. The tracks on the upright are similar to what I can see on your video. Except that I didn’t see the Marboro signs on the sides of the track. Hardcoregaming101.net says that there are substantial differences on the track layouts between the standard cabinets and the ride-on machines. Since my sit on is in pieces I can’t check to see what it tracks it has.
Hardcoregaming also states the Marboro signs were advertisements for Marlboro cigarettes and was censored from home versions but it doesn’t say if it was censored from upright or sit on cabinets that were put out later. I have a video of me driving it to the end of the last stage if anybody is interested in seeing it I can upload it. I can take pics of the boards if anybody is interested.
I would like to know if the cabinet that I have is rare or not. Any help I can get would be appreciated. Any help I can give I would be glad to.

What are the rom numbers/locations for each of the two sets? Pictures of the boards where we can read the rom numbers and locations from may be easier than typing everything up.
Does either set use an fd1089/fd1094 security cpu module?
Its possible one or both of the sets you describe are new and should be added to mame.

Here is an attachment with the Hang-on upright board pics. Where is the security cpu module located?

This particular romset is definitely undumped and not in mame yet.
EPR-6839.ic63, EPR-6838.ic51 are an older version of 68000 #2's code than anything in mame so far;
EPR-6848A.ic6, EPR-6849A.ic8, EPR-6850A.ic20, EPR-6851A.ic22 are an older version of 68000 #1's code than anything in mame so far either. (and given the A markings they're not even the oldest version code! There is at least one MORE set, older than the board you have, which we are also missing!)
While I suspect only those 6 roms are 'undumped' (and everything else probably matches one of the hang on sets in mame), I would consider dumping everything from that boardset, and note the icxxx locations each chip comes from. At the very least dump just those 6 roms.
This is most likely an older set than any of the hang on dumps in mame so far.

The romset on the upright board looks, based on the labels, like the same older, undumped set that the ride-on boardset you have has on it.
If one of the boardsets doesn't work, dump the other one.
Neither of the boardsets have any security cpus that I could see, unless I overlooked them.
