Im making a list of all the 90's based dos games that are reletivly new-ish that play great on xbox via dosxbox.
Alone in the Dark (Trilogy) - These are all in full cd glory & work great on the xbox with filters, great games & is great to finish if you have'nt already (hell im now play these to know abit more backstory to aitd4 playing via pcsxbox) B)
Need for Speed - This is a cd-rip. I got it working at a reasonably playable speed, although abit jerky. Its ok to play for a little bit but speed needs a improvment to have more better fps wise (maybe good if you got the 1.48 cpu xbox?) if anyone is instrested i'll get the settings posted up.
Disk World - This the non talkie version

This game works great with no problems & is highly great to finish for all the funny/silly bits in this game, i wonder if part 2 or 3 works also?
Grand Theft Auto - This is a cd-rip. This game works but was just so slow, i managed to muck around with a few settings & is playing better but nothing to play over along period of time cause of the jerkyness. I cant imagine how GTA2 will run. Play only to see GTA running on xbox for a few mins, also you can pick the san andreas island & there you go: gta san andreas on xbox.
Dark Seed - This is a non talkie based game but might of had a talkie version. This is a good horror click'n'pick game but is beaten by its sequal which is sadly a windows based game. The game is perfectly enjoyable on xbox, great to play with a guide
If people got there own to add, then please do so, i will try to update with as much games as i can, next will be special rpg that has many sequals/spinoffs to this day.
