* GS stubs (ps2_stubs_gs.inl): - Replace direct VRAM writes with GIF packet path - sceGsExecLoadImage: build GIF packet, set MADR/QWC/CHCR - sceGsExecStoreImage: GIF packet, processPendingTransfers, consumeLocalToHostBytes - sceGsPutDispEnv/sceGsPutDrawEnv: program GIF DMA Path3 (5/9 QWs) - sceGsResetGraph: GIF packet + writeIORegister for pmode/smode2/dispfb/display/bgcolor - sceGsSetDefDrawEnv: GIF packet layout, sceGszbufaddr for zbuf - sceGsSyncPath: processPendingTransfers, poll DMA channels - sceGsSyncV/sceGsSyncVCallback: return 0 - sceGszbufaddr: zbuf calculation (width/height blocks, gparam) Helpers (ps2_stubs_helpers.inl): - GsDispEnvMem: 5 fields (pmode, smode2, dispfb, display, bgcolor) for GIF layout - writeGsDispEnv: read-modify-write pattern - toDmaPhys: SPR (scratchpad) handling for DMA MADR bit 31 - submitDmaSend: chain mode (chcr=0x185) for sceDmaSend/sceDmaSendI/sceDmaSendM Misc stubs (ps2_stubs_misc.inl): - Add sceeFontInit, sceeFontLoadFont, sceeFontPrintfAt, sceeFontPrintfAt2 - Add sceeFontClose, sceeFontSetColour, sceeFontSetMode, sceeFontSetFont, sceeFontSetScale - Font stubs use GIF packets for CLUT and texture upload Call list (ps2_call_list.h): - Add sceeFont* entries between sceGszbufaddr and sceIoctl * added: added more scee font stubs in stubs misc fix: fixed flickering error when rendering in memory.cpp * fix: fixed linux build error
