Commodore PET entry for the Wild competition @Nordlicht 2023.
This game uses a newly developed graphics-mode called PECBM11 which provides a resolution of 88x200 pseudo-hires pixels. PECBM11 is based on PECBM (80x200 pixels) by Genesis Project's "A Bright Shining Star"-demo.
It updates the video-RAM char-pointers on each rasterline and works on machines with or without CRTC-chip. This is done by syncing to the VBLANK-bit first. Only the timing is slightly different for machines with CRTC-chip. The CRTC is then set to a display mode very similar to the original PET 2001.
If you want to use VICE make sure you use a version larger than 3.7.1-r44426 or just download a recent build from:
The official git mirror of the official VICE subversion trunk. - VICE-Team/svn-mirror
It will not work in VICE 3.7 or 3.7.1!
This was successfully tested on a 4032 and on a MINI PET 40/80.
If you use a MINI PET make sure to set the video output dip switches to 9" PET. Only in that mode it produces the same 260 rasterlines as the original machine.
I would welcome reports from useres with 3032 PET/CBMs. On older 2001s with 32K it will likely produce a strange picture. This is due to all the updates to the video-RAM.
