libTAS support (enhancement request)

[TwoSpacesSG]

There seems to be a decent demand for tool-assisted speedruns of J2ME games, whether it's Bounce Tales, Sonic or something else. Now that MahoLator development is on an indefinite break for a while by now, and the PCem setup seems increasingly nonviable, using FreeJ2ME-SDL with libTAS seems like an interesting prospect.

Aside from the elephant in the room, which is that savestates don't work, the libTAS chaining with FreeJ2ME-Plus SDL has been tested a bunch with Bounce Tales, and not so much with other games. Upon looking at other games, some strange issues can be noted:

• Sonic the Hedgehog Part One (1.0.46 for Nokia 240x320) takes about a minute to load Green Hill 1 upon selecting game start.
• Doom RPG (1.6.89 for Nokia Series 60) freezes on the first copyright screen while generating new lag frames.

Work on libTAS support has been postponed because FreeJ2ME is "not accurate enough", but it has been getting more accurate towards the end of last year thanks to AShiningRay's hard work, so this is more relevant than it has been.
