Weird thing about second shot from each set: scores are different, everything else is the same!

Status right now for the onlookers -
- Pong is sort of working? Attract mode mostly works, ball gets to end of playfield, and scores a point. At this point Player 1 score increments, but there's some slight graphics garbage, a stray line written to the score. Attract mode does not appear to repeat. During actual play, the ball bounces around, but when it gets to the end of the playfield, gets stuck at the end and bounces from top to bottom of the screen, apparently infinitely. Also, coining up during play restarts the ball back at the center of the screen, but continuing in its original trajectory (original bug/feature?). Finally, when ball hits the lower edge of the screen, it sometimes reappears at the top of the screen. (original bug/feature?) No sound. Average - 2.85 fps on Intel Pentium M 1.60 GHz, 1.2 GB RAM, 99% CPU usage.

- Rebound is very broken. Video appears "okay" (except for scores) until coin-up, when scores corrupt and bottom edge of playfield becomes corrupted. Ball never appears. Controls do not seem to do anything. No sound. Average - 3.32 fps on Intel Pentium M 1.60 GHz, 1.2 GB RAM, 99% CPU usage.

- Space Race appears okay before coin-up. Ships appear perfect, starfield, while it may not be accurate as Juergen says, is at least recognizably a scrolling starfield. Scores are slightly corrupt (as appearing in Juergen's screenshot). Compare Space Race screenshots versus Juergen's screenshot. However, after coin-up, controls never respond. Ships appear to stop moving, starfield stops scrolling. No sound. Average - 0.7 fps on Intel Pentium M 1.60 GHz, 1.2 GB RAM, 99% CPU usage.

So it's still very early days yet. No worries, Juergen!

I need a new home machine desperately, but the new work machine is a Core 2 Quad Q6600 with 4GB of RAM, I'll do some performance measurements there as well. I don't expect miracles.

Anyhow, performance be damned, we want to document these games before they all stop working.

-------------------------------------------------------

If you want to mess about at home, Juergen is uploading WIP Windows and Linux binaries to his website. You just need the binary plus the *.net files which describe the schematic of the game. Or you can compile yourself from source. Honestly, I doubt he's in the mood for error reports yet.

Usage: ttl [gamename].net

Fun Fact: Running "ttl" without any netlist file afterwards launches Pong by default!

Pong
----
Controls:
P1 - Up (Potentiometer) = "q"
P1 - Down (Potentiometer) = "a"
P2 - Up (Potentiometer) = "p"
P2 - Down (Potentiometer) = "l"
Coin = "5"

Other Games
-----------
Controls:
Start = "1"
P1 - Up (Direction) = Up Arrow
P1 - Down (Direction) = Down Arrow
P1 - Left (Direction) = Left Arrow
P1 - Right (Direction) = Right Arrow
P2 - Up (Direction) = "i"
P2 - Down (Direction) = "m"
P2 - Left (Direction) = "j"
P2 - Right (Direction) = "k"

The direction controls are perhaps to be used in Space Race.
