No problem, patch submitted
I'm still missing the TIAEN signal (2600 mode switch?), but I don't think that's needed as the driver is always in 7800 mode.
Thanks again, it is very much appreciated.
It would be very cool if down the road you launch a 2600 ROM under a7800, and the driver recognizes it, causing the switch to 2600 mode. I mean not just as some batch or patch to kick off the a2600 driver, but truly reading the ROM under the a7800 driver and in turn utilizing the 2600 emulation.
Which honestly, I'm not sure if what I'm stating is clear or just a matter of semantics. And if I recall correctly, it's not a matter of the 7800 reading a 2600 game, as it is looking for the 7800 signature in a game. If the signature is not there, I believe the instructions then is to disable Maria and kick off 2600 graphic mode.
In any event, obviously it is a minor thing and more important is fixing actual 7800 emulation specific bugs first.
