I *really* like those kind of games. Well done. I think with this graphics-engine you could do a nice port of OutRun as well. Maybe use +35K instead and loading from disk for different levels. The rest is nearly all there already.

Fun little game! Too bad about the removed SNES-controller support? Did you check the Petscii Robot's source code?

There is also a C64-code snippet David posted on his website some years back:

Maybe this can help you implement SNES-controller-support after all

Thanks for mentioning my "VDC FLI". As mentioned on CSDB in the production notes, this mode originated in the "Risen from Oblivion"-demo. With a lower vertical resolution or better timing it should be possible to do exactly 60 or 50 Hz in that mode, but calculating this with the necessary register-switch is a challenge on its own.

Too bad the REU can't access the VDC-registers and DMA only works in 1 Mhz-mode as mentioned in the REU-manual. Emulators are still catching up regarding VDC . Z64K should be the best one in that regard as you probably know.

I know the 128-version of "Attack of the PETSCII-robots" uses MMU zero-page relocation as well. And then there is the "Andropolis"-demo "Doomstage"-demo part that uses 2 Mhz as well as MMU-zero-page-relocation for speed-up.

Will have to take a much closer look at this game :-) Thanks for keeping C128 alive.

Works fine on my MiniPET 40/80. Make sure to set it to 80-column. Also do a system-check (SYS 40960) to see if everything is working fine. Also I'm using ROM 4.1 (all DIP-switches down), not that it should matter much.

Purchased. This will sure look nice on my Mini PET 40/80. I see it supports joystick,
does it also support the SNES-controller-adapter used by "Attack of the PETSCII Robots" by the 8-Bit-Guy? If not, maybe something for V1.2 ;-) Source-code for supporting the SNES-adapter can be found here:

Anyways, thanks for providing a killer app for the PET!
