Emulator have some leftovers from PSP emulator (like axinsnreplace), so core of non PS1 specific functions is the same as in PSP emu. Rest of emu seems to be "inspired" by mednafen.

=== Alternative solution - Disc Merge ===
Alternatively ps1 discs can be merged into single bin/cue. There could be potential limitations in file size because MM:SS:FF can only go up to 99:99:99 which translates to around 870MB. For sure this will be problem for games with CDDA tracks. For now there is no confirmation that this limit apply to data only games. How hard is disc merging depends highly on game we want to use. Parasite Eve is one of easiest games to do that since second disc check is triggered only if files from disc 2 are not present on current disc, which they are since discs are merged. Game also use the same EXE and PE file on both discs, and do not use lba based tables. So merging discs is literally repacking them into single disc. But different games use different approaches, games like MGS need additional patches to few files to skip shell open checks, and lba adjustments. For now Chinese Parasite Eve fan translation is only confirmed game that works (thx 苏宇 for playing whole game to test it).

POINT indicates successive track numbers, and PMIN, PSEC and PFRAME indicate the starting time of that track.<br>
POINT = A0, PMIN gives the physical track number of the first piece of data (PSEC and PFRAME are zero).<br>
POINT = A1, PMIN indicates the last track on the disc<br>
POINT = A2, the starting point of the lead-out track is given in PMIN, PSEC and PFRAME.<br>
POINT = 01 - 99 Index number within track.<br>
POINT = 00, Pause (2sec?, Also pregap?)

Emu build from 2023-Feb-17
=== The Legend Of Dragoon emu ===
Emu build from 2023-Feb-21

Universal dithering removal patch, works with every single game. PS1 cheats/patches are no longer required to disable dither pattern. To apply unself self file, edit, and sign it again after that. Alternatively you can use cheat engine, offset need to be adjusted to emu base then.<br>
''Replaces *and ecx, 7FFh* with *and ecx, 5FFh* to always remove dither enable bit on E1 write.''
*Emu memory offset: 0x50EA2
*Elf memory offset: 0x54EA2
Original bytes:
81 E1 FF 07 00 00
Replace to:
81 E1 FF 05 00 00
