(2008/03/01) Partial (and buggy) lighting support. Some cleanups. Starting gui for breakpoints and gpu (not working yet). Corrected callstack. Some fixes; more homebrew demos supported. Temporally skinning broken. Temporally shaders disabled. Updated binaries. Reduced size of the font used in dissasembler and memory viewer. Allowing reduce dissasembler window size; now imports won't overlap). Initial support of opening files (not working fine yet). Threading support currently disabled (I have to fix some issues). mstick and reflection demos not supported yet.
BTW: control+g in dissasembler & memory viewer to go to any address (can use expressions like pc+a0*4 or static hexadecimal adresses 0xXXXXXXXX or mixed 0xXXXXXXXX+v0*16). Double click in a register to modify it. Expressions can be used also in register changing. Supports decimal numbers, hexadecimal (ex. 0xF3) and binary (ex. 0b101)
尚不能运行商业游戏的psp模拟器,不过,有更新总是好的嘛...
