I plan on running my XBox in my low res EGRET II cabinet using RGB video, so I'll be running in the lowest possible resolution available to me. I don't know if the XBox is capable of 240p, but if it is then I already own Progear CPS2 board and the Ibara, ESP Ra.De. and ESPGALUDA PCBs, but I'd like to be able to run Ketsui (my favorite CAVE release) as the port runs too fast. I have all the 360 ports that I'm running in my Japanese 360, see. IIRC, some MAME dev was a bit surprised that the PGM hardware need lesser hardware to run smoothly than the NEO GEO. Of course, sprite buffers etc can eat up memory pretty fast and CAVE kinda pump out bullets at you. I'd love to play some more Garegga as well. I might be able to upgrade the memory (the soldering) but isn't it hard to find the parts today? I'll also try to find some video of the video settings. I'm still looking for an XBox locally as I'd rather not pay out the *** for shipping. Thanks a lot information and sorry that I can't be of more help as I don't have the hardware to test stuff.
