Heh. Yeah the crap one had to go through just to get emulated games running on old hardware...

Somehow Chrono Trigger was playable on a 486, but only if you disabled transparency (which made a couple of levels really tough to navigate) and had sound disabled. This was with ZSNES on Win95 I think?

I remember that in Chrono Trigger there is a part in the future where you need to input a specific button sequence, and in one of the early version of ZNES it wasn't working, it was maddening at the time :).

It wasn't ZSNES, it was your keyboard not accepting input from three keys at once !!! I know because I remember this exact thing.

It was actually neither ZSNES or my keyboard, but SNES9X :)

- This time really fixed Allegro library keyboard handling (DOS port); it was missing key some presses/releases (was stopping Chrono Trigger Left + Right + A button combo from working).

ZSNES certainly had the L+R+A problem, too. [1] I assume the default key mapping hit a failure case with some common limited-rollover keyboard design, but I've never bothered researching it. It's possible it was caused by Allegro, as well.

I remember playing Chrono Trigger on an early SNES emulator that didn't support alpha layers (possibly ESNES), and when you got to the future, you had to know to disable layer 3 so that the fog wouldn't just completely block out the world map.

The transparency problem was common enough with ZSNES to make it into the FAQ: https://github.com/bazzinotti/mac-zsnes-1.36/blob/master/dos...

Yup!

Evem today some emulators have trouble with this :)
