oh, and I have to rectify a previous announcement: even our sloppy BSX implementation is enough to support the character data in Same Game, by just dropping samegmcc or samegamecd in the -cart2 slot available when loading samegame...

Same Game + Chara Cassette, Bomberman flavor


and Momotarou flavor


and Same Game + Chara Data (which adds Tengai Makyou characters)

Running Super Mario Kart, it's 25% slower than on the old code frown
But SMW2 runs about the same slow speed as on the old code :P

I did see some changes which made it look like a lot more was being pumped through the memory system, although didn't analyse them to see if it was just the diff tricking my eyes.

would explain the nasty slowdown if it is the case tho.

passage through memory system is more or less the same, only checks for addon chips are now done in mess/drivers/snes.c instead of mame/machine/snes.c
also the code is quite specular between snesnew and the 'legacy' drivers snes/snessfx/snesdsp (which are still as fast as before)

the real culprit is probably the slot code: even if the passthrough is installed only once at start, for whatever reason the access to the rom through the slot device slows down as if some check is performed at each access
I had been told that once all drivers are modernized this could improve, but every time I tried to find where the problem was exactly I got lost in the various casts

The cart is protected and protection is still not emulated (which motivates the supported="no" in the xml list).
The accesses are similar to Pokemon, which is now emulated, but not the same...
