Both were detected when testing 1337 under a real machine. The first one is a bug in the program which is not detected in Euphoric as it did not emulate the PSG IO port direction (Oricutron does not do this either, so I raised an issue).
Code: Select all
Build 1011 changes ------------------ - now emulates the PSG IO-port direction bit. This is not useful (it prevents the keyboard to work), but it removes a difference between the emulator and the real thing. - also emulates the propagation of ground voltage through the keyboard matrix intersections when several keys are pressed simultaneously. Again it's not really useful (it will even make wrong key detection in some conditions), but at least it behaves like the real thing.
The second is a problem with the Oric hardware and how the keyboard matrix is connected. I will post details (provided by Fabrice) about this on another forum (hardware).
Just in case you want to upgrade! http://oric.free.fr
