This page is designed to allow for a quick look over all the drivers with a GAME_UNEMULATED_PROTECTION flag (but still working) by giving, as much as possible, an idea on the amount of effort needed to fix them.
kodure, legion, legiono, terraf, terrafa, terrafu - Needs better simulation or decap of the MCU / blitter.
primraga - is pretty close, but not quite perfect. There are some sprite offsetting issues still and I'm not 100% sure the gameplay is all there.
primrage - as above
tmek - is interesting. We have a prototype version that plays well, but has no matching sound ROMs so you don't get sound. Then we have a non-prototype version that doesn't play correctly, but has fine sound. In theory, it might be possible to see the decrypted data in the prototype version and understand the process, but not much work has happened here.
