I got curious and gave it another shot using another JVS interface and the ODE I mentioned. Tried two HDD images, Battle Gear 3 and Gundam vs Gundam NEXT (which is an 80GB image). I *can* get Battle Gear to start and show "Boot 01" (sometimes "Boot 02" and "Boot 03"), which I believe is just it trying to read something. Looking at the trace feature, I can see it requesting and receiving up to cylinder 8192. Nothing else is reported by the System 256, it just stops.Some games can boot with any or no JVS and the drives aren’t copy protected, problem is the way they work
With GvsG Next, I could get it to boot to an error about configuration and network, was able to interact with it, but now all I get is "Handle Error", which I believe is due to it requiring specific hardware controls. So, this ODE *does work*, but something else is still missing.
