Lightrec dynarec
|
|
For some Eboot .PBP game images, when loading a savestate, a zlib error
like 'uncompress failed with -5 for block 5383, sector 86132' would be
output to stdout/stderr. The savestate would still be playable, though.
Traced it down to cdrFreeze() failing to convert cdr.Prev from BCD->int
when calling ReadTrack(). Note that the odd 'cdr.Prev[0]++;' line seems
to be someone's hacky way of forcing ReadTrack() to avoid skipping what
it thinks is a duplicate sector read.

This permits the Lightrec dynarec to emit better code.

Basic Guncon support
|

same syntaxis as beetle-psx, name the sbi file after the pbp and append an underscore and the number of the disc at the end.

- silence a few more truncated warnings
- change "disable" to "disabled" in core options
|
|
- Save files for games that are suppose to work with HLE bios are now corrupted from the last HLE BIOS improvements PR.
- This only affects memcard 2 slot when enabled and used. Saves on memcard 1 are fine since those are directly handled through the Libretro API.
- This is fixed by adding the missing SaveMcd() to buwrite().
Tested on Wild Arms and Breath of Fire III
NOTE: HLE bios is still not compatible for most games. For example, memory card save functions are broken or does not work at all. Most of Konami games i have tested does not work with HLE BIOS for memory card saves.
|
|
- This just silences some [-Wpointer-sign] warning from last PR
|
|
- Wild Arms EU and US version has non-standard string (probably for region protection) causing auto-region detection to fail and wrong CDROM info in log.
- This fix sanitizes the string name to remove unneeded characters ("EXE\" in this case that comes before the serial-number). This would sanitize the CD-ROM info in log as well.
|
|
-strncpy replaced with strcpy and memcpy where appropriate
|
|
- Increasing the maximum size of destination char array to x2 to silence this warning.
|
|
|
|
|
|
- this should silence warning for another PACKAGE_VERSION define used for flac
- PACKAGE_VERSION is not used within pcsx other than version logging. Savestate does not check for this and is using another define for savestate version number.
|
|
- Merge update from https://github.com/libretro/pcsx_rearmed
|
|
- at least one game (Wild Arms) is continouos spamming the log window. Silence this in a way that its easy to enable when need to.
- Remove unnecessary message in Makefile

HLE BIOS improvements (based on nocash doc, pcsx4all, upstream pcsxr etc...)
|
|
Notaz said this could corrupt the emulator (even though
the console allowed this and it was a bug) so limit it to 0x3FF.
|
|
This should work as intended now.
|
|
This fixes Looney Tunes Sheep Raiders.
|
|
According to nocash PSX doc, ChangeThread and CloseThread should
always return 1. Fix it accordingly.

See Garbage Area at Address 00000000h in Nocash PSX Specifications for more inf>
R-types will refuse to boot if psxM[0] is zero.
Fade to Black can crash upon memory card access if psxM[5] is set to the wrong >
Crash Team Racing will refuse to boot if psxM[2] and psxM[3] are not zero.
(Previously, that region of memory would be overwritten above. No explanation why.)
It's set as such according to nocash :
[00000000h]=3C1A0000h ;<-- but overwritten by 00000003h after soon
[00000004h]=275A0C80h ;<-- or 275A0C50h (in older BIOS)
[00000008h]=03400008h
[0000000Ch]=00000000h
Note that setting 00000000h to 00000003h doesn't work for R-types.

I already fixed this for bufile :
ptr = Mcd##mcd##Data + 128 * (nfile + 1); \
instead of
ptr = Mcd##mcd##Data + 128 * nfile; \
But i forgot to also fix psxBios_firstfile accordingly.
So nfile would still start from block 2 and it would
cause all kinds of issues.
This was the original comment on pcsxr codeplex
as my patch was based on it :
"The HLE-Bios start to read memory card blocks at block 2. You need to change
ptr = Mcd##mcd##Data + 128 * nfile; \ to
ptr = Mcd##mcd##Data + 128 * (nfile + 1); \
for #define bufile(mcd) { \ and changing nfile = 1; to nfile = 0; for psxBios_firstfile() { // 42 Starts numbering slots in the right position."

Thanks DmitrySmagin for the fix.

Pretty much identical to get_card_status except it's supposed
to wait until a non-busy state occurs.
|
|
- Remove extra ffile, pfile.. as it is declared elsewhere.
- Remove extra condition as it's already being handled by pad_stopped.
- Remove n variable from function (pcsx4all did this) as it's useless
and documentation doesn't seem to specify it's needed.

Merging never-merged fix by Solus for Parasite Eve. I also fixed some GCC warnings
about dir->name going out of bounds too.
We also make sure to only add '/0' if string is not full and right after the last character in the dir array.
This fixes saving/loading in Parasite Eve II, Parasite Eve.
It also fixed regressions for the LEGO Racers where other games would break,
meaning this should be the proper fix for saves.
We're also using our own strlen implementation to avoid any issues or
relying on the libc's own strlen.

We are already doing that in WaitEvent. According to nocash documentation,
this also applies to TestEvent as well so let's implement it.
