Hello Jens,

can you give us the Guru number ?
Is it with KickStart 1.3 ?

Regards,

Frederic

Hey, cool project! Do you have any project page?
Are the sources available?

Cool indeed. Would the older Cave games work, I wonder?

Nice work.

What are the differences between this implementation and the actual arcade hardware? Did that have a 16-bit bus?

I presume that the 1280x1024 VGA output is not generated by the game, but by some form of scan doubler/quadrupler, capturing the simulated game video hardware's output?  I guess adding Scale2x, etc, algorithms in hardware to this module doesn't touch the arcade game hardware at all, and can be re-used for other games in the future?

Hello,

it is funny to see this thread resurfacing after 5 years...
IIRC, the original HW outputs a 256 x 192 screen. The Scale2X algorithm increases the resolution to 512 x 384. It is then scandoubled to 1024 x 768 (actually 768 x 1024 since it is rotated by 90deg.)
The core can execute few more games like 1943 Kai, Gun smoke, Sidearms, Commando and Black tiger.
The sound is still missing but recently, I started working on FM synth yamaha chip core.
Regards,
Frederic

This is planned.
The problem is I wrote that stuff 5 years ago and used a SSRAM controller.

So where is the code? I see this so often with people developing cool stuff on FPGAs, they show a video tease of it working but don't post the code so anyone else can play with it. Virtually every microcontroller project you see someone showing off online has the code available, or at least a hex file.
