Crashes
TI-99/8 Extended Basic II with selected floppy controller locks up on start
Symptom: When selecting Extended Basic II, the floppy is accessed, and then the emulator is trapped in an endless loop. This does not occur if no floppy controller is active.
Reason: The TI-99 DSR in Extended Basic II assumes that PABs can also reside in CPU RAM. However, this is not supported by the DSRs in the expansion cards. Accordingly, the PAB is not found, and Extended Basic II does not properly handle this case and crashes.
Workaround: Any other cartridge (like Editor/Assembler) works, so you have no floppy support in Extended Basic II, and this cannot be repaired, since the error is in Extended Basic II. Hexbus devices may be supported, but this is not available in MESS yet.
Failures
Geneve fails to boot from disk
Symptom: The Geneve does not boot from disk when the disk is inserted too late. Once the "CANNOT READ FROM FLOPPY DISK" appeared (because there was no disk in the drive), it fails to read the disk on retry.
Workaround: Ensure that a boot disk is inserted when starting. Or try to pause the emulation (partial mode, press p), insert the disk, and continue.
Geneve joystick
Symptom: Joystick in native mode has been reported not to work. Needs verification.
Keyboard issues with natural keyboard
Symptom: Natural keyboard keyboard sluggish; key repetition interferes with TI key handling
