Doom8088 can run in 64 KB. The commercial GBA port managed with 256 KB (ish) and some megabytes of ROM. That inspired a modern full-featured source port from prBoom, unhelpfully named GBADoom. And this delightful maniac finally got it to compile under gcc-ia16. He’s been whacking at it for months, and it’s getting to be genuinely good on a 286.
The real reason this can’t run Doom is that it gets three operations per second.
