Hi, so im enjoying experimenting with the overclock feature in the mame on screen display/slider controls menu...
the two most popular games it seems which apparantly benefit quite a lot from overclocking i understand, are double dragon and metal slug
can anyone list any more games which really do benefit quite a lot from overclocking?

I never tried this feature before in MAME. I just might have to see if it helps knights of valor seven spirts

Stun Runner, Hard Drivin...15-20fps is for wimps..
As for other Neo Geo games, I always crank up the cycles on Pulstar and Blazing Star

im confused, i thought hard drivin is a 60hz game
ps. by overclock i mean, overclock the actual cpu of the videogame hardware in question, not overclock the pc itself which mame is being run on... (so eg. the game double dragon is suddenly running with twice as powerful cpu as it did at the arcades...)

note: fyi i think u need to turn on 'cheats' before u get to see the overclock option....

Metal Slug 2 benefits more than the first.
Also, how do you save the settings? The settings that I change in the slide doesn't hold and I don't know what should I put in the game.ini.

Lol..i knew what you meant as regards overclocking via MAME..and not the PC.
As regards to what 'hz' a game runs at, that has little bearing on the actual 'internal' frame rate you see the game run at, hard driving is only updating the games polygon enviorement at about 10-20fps.
Afterall, Neo Geo games run at 59Hz, but the slowdon can cause the games internal frame rate to slow to a crawl when it reaches the hardwares on screen sprite drawing limit.

That's intentional. Games may appear to work OK at higher overclocks, but we want to make damn sure you know each time you apply one so overclocked results stay far away from MAMETesters.

Understandable, but is there a way to make a specific game.ini? If yes, how should be the structure?

you can create a game.ini of course, but since overclock is not a MAME option, you cannot change it in an .INI file. You can only activate the cheats so you'll have the sliders for overclock activated every time you play. Though it's useless since you can enable cheats globally for all games.

neo geo i can understand (ie. slighty deranged programmers) but im horrified at the legends who are atari releasing an arcade game on such mismatched hardware that they only get 10-20fps
or maybe hard drivin runs at the exact speed atari wanted all along... guess we'll never know

The game runs at the best speed the hardware was capable of in the late 1980's.
If Atari had the hardware that could run the game at a solid 30 or 60fps available to them at a price that was affordable to put in a commercial arcade machine, they would have done.
The Hard Driving hardware was highly advanced for the time, it uses 4 CPU's..from system 16:
These games use many CPUs and many boards in many different combinations, but all games had the same basic features.
Main CPU : 68010 @ 8 MHz
GSP : TMS34010 @ 48MHz - Rasterizer : to render the polygons and graphics
PSP : TMS34012 @ 50MHz - (labelled SCX6218UTP) to expand pixels
MSP : TMS34010 @ 50MHz - (optional) to handle in-game maths calculations
Video resoution : 512x288
Very expensive for the time.....to put in a CPU that could triple or quadruple the frame rate, would have been just too expensive.

Yup. The base Hard Drivin'/STUN Runner hardware was designed in 1986/87. They were *seriously* pushing the technology at that time.

So assuming that I already have cheats enabled in mame.ini, can't I set something like "Overclock CPU maincpu 120%" inside, for example, mslug2.ini?

Nope it's a cheat and you can't auto-load a cheat...

I know it sucks  I once overclocked Contra to 125% and I think it was much better...... no lag and all.
But then everything was back to normal once I loaded it again.

The entire PE Plus driver. Slowest credit count of a coin operated machine in history, ironic since the games are designed to take your money!
In fact, just run the games with max speed/frameskip, fixes all of the problems. Apart from still having to bash the hell out of the credit key to feed the thing. At least on the Aristocrat video poker games, they allow you to continue to insert coins (as credits) beyond the max bet, or at any time during the game in fact. Having separate coin and credit counters is kind of ridiculous IMO, the games should have been designed to add coins as credits, not just increment the bet like an old style slot machine.

Umm, no. Double Dragon is notorious for severe slowdown on the PCB.

analyzing this video,I see that attract mode is faster than in mame. Is it normal slowdown in mame?

I overclocked Double Dragon once and it was weird..... some parts were still slow as hell...... some parts were too fast...
I tried many settings but I can't get it to play super smooth.
Even the "faster" bootleg isn't that much better.
I guess I'd rather play the NES version instead
