Tournament Table VCS conversion

[Wickeycolumbus]

The Tournament Table was an arcade game based on expanded VCS hardware (6K max ROM, dual RIOT chips). For the past week or so, I have been working on converting it to play on a standard 2600 with some success. Since it had two RIOT chips, it had a whopping 256 bytes of RAM. Because of this, I ended up using the F8SC scheme. I ended up putting most of the kernel stuff in bank 1 and the logic in bank 0. The conversion is about 70% done (I still need to deal with the DIP switches and controls). I plan on making a title screen where you can set the DIP switches and game. Special thanks to Thomas Jentzsch for posting a partial disassembly of the original ROM

 

The current ROM seems to always start up in Breakout/PAL mode, sometimes skipping the title screen. Breakout is for the most part playable, save for the fact that it crashes at the end of the game. To play, set P0 controller to Joystick, P1 controller to Paddles, and color mode to B & W (this is not needed, it just makes the colors appear nicer). Paddle 3 will control P0 (the black paddle), and Paddle 2 will control P1 (the white paddle). Joystick up is the button for P0 and down is the button for P1. Let me know if you have any trouble getting it to work or of you have any comments/suggestions

 

Here are some screen shots:

Impressive.

Nice!!!

Excellent work Wickeycolumbus!!

 

Finally someone who's converting the Arcade version to the VCS. Since i'm no programmer,

i can't help you out.

 

But if don't mind a suggestion (after the conversion is done), could you add color ?

Just imagine, a better version that the original arcade game! Keep up the great work!

Thanks! Adding color should be simple. I haven't worked on this in a while, but I do plan to finish it at some point

Cool! Can't hardly wait to see the finished result! =)

'Cause it would also fun to see the arcade version in color. I have 2600 spare parts to make a harware

replica of the Atari Tournament Table and seeing this arcade game in color (with also the VCS conversion)

would be awsome. Doing the hardware replica wouldn't take long since there's only an extra 6532 to add

to a VCS.

 

Keep up the great work!

Depends what you mean by "wouldn't take long." Compared to designing your own circuit board, maybe not, but there would be a lot of hacking involved.

 

You need to cut the chip select lines on all chips, figure out the new address decoding logic for all existing chips since TT has more addressable ROM, and figure out the decoding logic for the new RIOT chip. At a minimum, a PLD programmed with the new logic, or some TTL chips would be needed.

 

From there, you need to figure out how controllers, DIP switches, coin slot, and anything else connects. It may be necessary to remove more components from the board if they get in the way (such as paddle dumping caps and joystick buffer ICs.)

 

Sounds like a lot of work to me.

Yes, that is what inspired me. This should be a 1:1 port of the original, so it would be much easier to just get a cartridge of the port
