Extremely simple design -- a 8080, two joysticks and a beeper. Black and white output. A single cart with five games (Breakout, Tetris, Snake, Xonix, Choplifter). Soon in MAME smile

A previously unknown hardware variant turned up and was dumped, plus there's firmware source code. Some WIP:

Merging that code into mainline will take some doing, it's using a hacked T11 core and I don't have a clear idea how to rework it yet.

Code
# adapt to different memory layout on the KES; makes controller test pass
wpiset 4a,1,w,(wpdata==1 && w@92b==0xe),{ logerror "Hacking IOPB (xfer buffer)\n"; focus 0; temp1=920; w@(temp1+0xe)=4000; w@(temp1+0x16)=600; go }
bpset fcf76,1,{ cx=600; go }
# ACT passes transfer length 0, fix it
wpiset 4a,1,w,(wpdata==1 && b@92b==5),{ logerror "Hacking IOPB (read and verify)\n"; focus 0; temp1=920; w@(temp1+0x16)=200; go }
# firmware crashes, use a different command to fail hard disk test
wpiset 4a,1,w,(wpdata==1 && b@92b==3),{ logerror "Hacking IOPB (read id)\n"; focus 0; temp1=920; b@92b=8; go }

I suppose the next best thing is HLE, since hardware docs for actual storage controllers (iSBX clones) are missing.

Bowling and hedge maze simulators on rt1715w -- these might be original, but I didn't look very hard in the CP/M game archives:
