and this latest release introduces MIDI support code crafted for the Roland MT-32. While the lowly PC speaker was first on the list, I very quickly added Tandy/PCJr sound, the original Creative CM/S (aka Game Blaster), Adlib/FM. In addition to the special video mode I've gone through and added support for a wide array of early PC sound cards. move the high score and score off to the side, and there's enough height left over for the playfield, number of lives and level bonus symbols. Thankfully much of this type of maze-game logic is based on a 28x36 screen grid, with the playfield only using 28x32 of that. made this one a really good challenge for me. The original 224x288 graphics not only fit poorly in PC screen resolutions, compared to the oddball semi-graphics mode I'm using it's almost three times the pixel count. It's actually kind of funny how the original Pac Man fit the code into a tiny little ROM on a much less powerful 3mhz 8 bit Z80 processor but it had some really hot video with hardware sprites - on the PC the CGA, EGA and even VGA cards lacked hardware sprites, meaning everything has to be handled in code on the processor. In todays age of 'just throw more hardware at it', cutting the code down to the bone was a refreshing change. The minimum target system I set for the project was an original 4.77mhz 8088 class machine with only 128k of RAM. Since that original demo it has grown into a full fledged Pac-Man type game.

I made a Turbo Pascal 7 unit to implement the undocumented 160x100 16 color graphics mode on the original CGA card - and decided to make a game with it. This game started out as an expansion to my Retrochallenge 2011 Winter Warmup entry.
