I updated the wiki a bit to reflect the rom directory options and status.

I appreciate the work that has been done to document the good/bad/ugly ROMs. Now that other emulators are available, and interest has shifted to the consoles, it would be good to know which ROMs that currently don't work well in MAME are actually desirable (as in, unique or best-of-kind options compared to console or native game options).

I noticed some mention of rotation/portrait. As has been seen in a previous update, portrait mode via rotation is an option available in the settings (right volume button->Video Options->Rotate) but makes the default control scheme confusing at best. The way to get these games playable is to figure out the best way to handle controls for them, possibly make a controller file (for you mame veterans), and share it. I will be adding an option to rotate joystick events to accelemymote next update so the accelerometer can be used for that purpose.

I have been poking at the GLES issue but the magnitude of the code in MAME is daunting, and i think i need some GLES development experience on the side before i will know what to do to add GLES support to MAME in a generic and sustainable way. Finally, with all the emulators now online, i'm not sure the interest is here to justify the work on a diminishing return, time that could better be spent on original development or porting actual games. This is where the feedback requested above would be handy: what nice games that should run on MAME (i said to expect pre-1990 ROMs that work well in desktop MAME) and can't really be found elsewhere are not currently playable?

Edit: Okay, galaga88 from the above post. There's one anyway.
