A guide to running IRIX 6.5.22 in MAME
- mrlonglong 6y agoThis is quite interesting. I do wonder if you can bootstrap Linux on it.
- FlyMoreRockets 6y agoI expect you could. Then you could install Win3.1 running on DosBox. Or even a recursive MAME install...
- unixhero 6y agoThis is not just interesting, but amazing!
- rbanffy 6y agoIt's surprising the performance on modern hardware is so low. I would expect the GPU emulation to suffer, but not CPU.
- m463 6y agoI recall mips being pretty different, including being both-endian. But there seems to be quite a number of mips emulators: https://www.linux-mips.org/wiki/Emulators https://www.linux-mips.org/wiki/Emulators but I can't seem to find any perf numbers or capabilities (for example QEMU probably does just in time emulation, does mame/mess?)
- spijdar 6y agoMAME notoriously aims for accuracy over all else. In this case, I think it's just MAME using slow but precise "cycle accurate" emulation techniques as opposed to QEMU, which uses TCG to translate guest to host, and takes a few performance shortcuts. Just speculating, though.
- rbanffy 6y agoIndeed - they do The Right Thing. A dream of mine is to build a compiler that reads MAME code and spits out VHDL.
- lasereyes136 6y agoIrix was my first Unix, I used it in a lab at school. It was wonderful and much better, at least from a visual point of view, than the other Unix flavors at the time. I learned X-Windows programming on it and really loved using it.
