http://code.google.com/p/yaupspe/ YAUPSPE is a PSP emulator, based on Potemkin, coded in ANSI C and that uses SDL. It's still in development, so don't expect to see a game running — only some PSP SDK samples barely work. Changes： r38 Fixed for win32 r37 Added memory fix in case the address is not a 2 multiple for mem_write16 or 4 for mem_write32 Fixed screen (now there's no more strange colors at some places on the screen) Fixed another time chdir & directories starting with / (now it should work as expected in all the cases) r36 Added some syscalls Fixed display (now all the screen shows, and the text doesn't overwrite) Fixed VADDR & IADDR in GE (but GE still doesn't work) Added sceIoMkdir Fixed jumping after _sceKernelReturnFromThread (the "PC compensation" seemed wrong); not fatal but removes strange memory errors r35 Finished cleaning HLE: (fixes issue 8 ) - removed syscall numbers (useless in most of cases) - re-organized by library - added the possibility to see when an unknown NID was called Started implementing sceMp3 Finished fixing I/O (write, seek, and chdir) (fixes issue 13 ) Fixed awful things in DirFileSystem Fixed path without drive name (starting directly with /) for ms0: (the path without drive was working, but it broke ms0:) r34 Fixed some instructions : makes the power and controller samples work mostly The emulator can now quit normally (pressing escape or closing the window) during a GU interpretation r33 Switching GPLv3 to GPLv2 (Potemkin uses GPLv2, and I prefer it r32 Changed project name from pspemu to Yaupspe r31 Fixes in interpreter: - divided Mftv VFPU function into mfv and mtv (the other will follow) - removed useless emuhack - added break (called when dividing by 0 by the program) - fixed some branch instructions - cleared some parts - added some non-implemented instructions/tables in the tables - removed Emu and Cop2Rese tables Fixed ms0 reading Fixed strange things in sceIoLseek Fixed wakeups Cleared __KernelLoadELFFromPtr Added sceCtrlPeekBufferPositive (but just a copy of sceCtrlReadBufferPositive) Various other cleaning r30 Added syscalls Added unrecognized stubs test Cleaned display Fixes in GE Re-organized host The emulator can now quit in a GE interpretation (useful for the infinite loops) r29 Fixed mult instruction (makes now text write correctly Some fixes in controller r28 Fixed threading for jr (last method was wrong) Fixed removing a thread Fixed memory map problems (that caused most PSP SDK samples to crash before main function) Fixed drawing (there was a strange mess with pspframebuf defined everywhere...; now some letters draw in some PSP SDK samples) Now draw display at a timed rate (~30FPS) Various adds in HLE r27 Better thread & memory errors debugging Simplified the DSP Interpreter code r26 Much work on GE Made mult instruction work again using the non-C89 method (to be fixed) Fixed mounting PBP's directory r25 Finally fixed all tabs for real r24 Fixed more HLE functions in callbacks, memory (partially, missing alloc), IO (missed one in last commit) r23 Finished fixing Semaphore, Thread and partially IO (missing things in metafs) r22 Added debug for memory errors (writes the last instruction) Fixed all semaphore functions Finally fixed all the tabs r21 Fixed Makefile — missing -lncurses r20 Woops, added log.c r19 Added Mingw32 Makefile r18 Fixed compilation in -pedantic Fixed for Windows Reorganized logging — now -d (ncurses debugger) and -lLVL (debug level) works perfectly, with or without -DNCURSES Fixed tab => 4 spaces and spaces after commas (mostly for logging) Updated --help Added a few HLE functions Maybe some other minor changes r17 Fixed portability for win32 (tested with mingw32 and wine) Fixed leaks Various clean up Added lv.s VFPU instruction Fixed jumping to too big addresses r16 * NID Checker added * Fixed splitpath * Added missing sceImpose files * Updated README r15 Added some instructions debugging Added pref instruction (the 'hit in wipeout') (but not implemented) Added a lot of HLE functions & NID r14 Some fixes in I/O, rendering, some syscalls added, added 'p' key in ncurses debugger to run the program (SLOW), and various other fixes --
