Manxtt: crashes after the title screen, the TGP is the cause Manxtt: no escape from "active motion slider" tutorial (needs analog inputs), bypass it by entering then exiting service mode
Vstriker: shows some attract mode, then hangs OK (controls may be wrong/missing/incomplete) zeroguna: stalls after some seconds of gameplay vstriker: countdown in team select goes way too fast. vcop: tilemap priority bug at stage select screen vcop: sound dies at enter initial screen (i.e. srallyc: opponent cars flickers like wild skytargt: MAME hardlocks after disclaimer screen pltkidsa: after few secs of gameplay, background 3d disappears and everything reports a collision against the player lastbrnx: eventually crashes in attract mode, geo_parse_nn_s() is the culprit apparently lastbrnx: uses a shitload of unsupported SHARC opcodes (compute_fmul_avg, shift operation 0x11, ALU operation 0x89 (compute_favg)) lastbrnx: uses external DMA port 0 for uploading SHARC program, hook-up might not be 100% right fvipers: enables timers, but then irq register is empty, hence it crashes with an "interrupt halt" at POST (regression) dynamcop: stalls at stage select screen desert: several 3d bugs, presumably down to FIFO daytona: runs at half speed in gameplay Sound comms actually passes thru a 8251-compatible device, hook it up Inputs needs device-ification and clean-ups Games also tends to stalls at some point, culprit might be when i960 tries all Model 2B games: FIFO comms looks way wrong, and 3d is mostly missing/incomplete.
