I remember you saying you wanted to do Body Harvest but it doesn't work well on emulators. The good news is that a video plugin called Shunyuan's SoftGraphic 1.5.0 seems to fix its issues. The bad news is that software graphics emulation takes a ridiculous amount of CPU power and I can't run it without lag.
If you do decide to do it, you might want to show the little-known disabled cheats described here: https://tcrf.net/Body_Harvest
I actually went to the trouble of looking through the memory to find the cheat strings, and only found that page after I enabled them myself. The sad part is that so many cheat codes sites have listed an invincibility cheat that doesn't work at all, ever since the game came out. The real one gives you this fancy blue shield and everything.
