PSX : new features: - bilinear texture filter (plus settings for 2D detection and filter strength) - 24bit rendering - 8 Mbyte RAM option(mostly for homebrew) fixes/changes: - CPU: implement partial cache line fetch for BIOS - DMA: fixed a bug where the DMA would read up to 4 additional words from RAM in background that are never used - DMA: fixed...

So you mounted it yourself? Have you turned off automount then?

Otherwise your mount for slot 1 will be overwritten every time you load a game.

Did you open the OSD and it was saying "Memcard Status: saved" ?
OSD must be opened even with autosave.

There was no memcard change since the last official release.

Good find.

Cheats should be automatically turned off as soon as the data cache from turbo is on.
Due to an oversight of me that is not working anymore, i will fix it.

All polygon will filter all Polygons, while the setting Dithered and Dithered+Shaded will filter only polygons that are dithered( and shaded). The use of that is mainly for some games that have e.g. 2D backgrounds or other elements that look bad when filtered, so you can leave them out. I usually only use All polygon + 2D detect ON, that works for ...

It's by design and a limitation of the texture knowledge: the gpu doesn't know the size of a texture at all, so all i can do is assume that the texture is inside the size of what the polygon itself is using. E.g. polygon uses texture coordinates of 7..13, but the texture is in reality 0..15. Then i cannot know it's 0..15 but only use 7..13 That als...

Cannot reproduce that, even with vsync adjust 0 jump and boxing seems instant.

I guess you ripped them to a single bin with 1 cue listing multiple tracks?
That feature was added but left unfinished and buggy I fear.
The official bin support for psx is only for multiple bin with 1 cue.

You can either wait for it to be fixed or convert the files to multiple bins or to chd

Implemented now with 25,50,75 and 100%

Made some comparison shots of how it would look in different steps. (first is off, last is current)

Please tell me what you think about it.

When using fixed Hblank, the aspect ratio should be right. It was verified with HDMI to modern display and VGA out in parallel on a SONY PVM.

It doesn't mean that all circles are true circles, it only means that it looks like it looked on a CRT from the 90th.

It seems the game cannot hold it's 60fps in this scene, which results in tearing due to a missing frame.
Slight CPU turbo already helps.
Setting to PAL reduces the overall speed by 1%, could be enough also.

Cannot say if the real hardware also has this performance issue or not.

It maybe changed when the feature to load different games was added...i never tried with more than the normal bootrom

Not sure about PSIO, but XStation is likely more compatible as it only has to exchange the CD part and does a great job with it.

Hard to compete with rebuilding everything against "only" CD
(CD is maybe the hardest part, so hopefully that doesn't sound rude)

I didn't fix anything recently, so maybe it was just random?

Yes, some are listed in the github issue tracker.

Most of them have a workaround, so totally not working are only very few.

PSX : features: - implement 3 different turbo speeds - Move datacache into CPU -> speedup when using turbo setting "high" fixes/changes: - fixed memory card loading edge case leading to memory card data not being available - fixed wrong savestate slot index when loading core - fixed edge case where loading a savestate would hang up the c...

Maybe you only saved in GBA with savestates and never with ingame saves?

You need to copy the save on the sdcard from saves/GBA to saves/GBA2P

Memory card is no dedicated slot, despite how it looks on the console, it's using the same lines as the controller in the same port.

It's not fully impossible, but WAY too much effort and could lead to random problems depending on the connected gamepad.
And if there is something people would hate, it's random problems with their saves

PSX : Games affected by fixes: Spyro 2+3 PAL, OpenBIOS, Red Asphalt USA, Next Tetris, Tom & Jerry PAL, Loaded, FEDA 2, GTA PAL, Gouketuji Ichizoku 2, Suiko Enbu, Battle Arena Toshinden new features: - always fill turbo data cache -> allows turbo to be switched on/off at runtime changes/fixes: - CPU: implement instruction cache valid bits for e...

GBAs have various ways to communicate with each other and most likely only 1 mode of them, which is covered by 90%+ of the games, is really supported currently.

Maybe this will improve in the future, but i cannot promise anything.

PSX : Games affected by fixes: Dino Crisis 2, Suikoden, Vagrant Story, GTA, Transformers, Micro Machines, Rugrats - Search for Reptar new features: - option for fixed CD speed added(1X-8X) - optional hack to limit CD read speed to capability of the game -> allows to use 8x CD speed in more games without CD read overflow - add gamma feature from fr...

GBA2P : - option to load different games for player 2 - option to duplicate saves from player 1 to player 2 when loading a game - fix/remove automatic reset of audio select mode - fix Sound DMA empty fifo handling - fixed edge case where the last pixel of the last sprite per line could overwrite a pixel of a previously drawn sprite - update framew...

GBA:
- fix starting the core with "Sync core to video = off"
- autodetect RAM now has fallback to DDR3 when romsize exceeds SDRAM size
- add OSD option to allow GPIO features for romhacks(e.g. RTC and Rumble)
- add gamma for 2x rendering
- correct color 6 to 8bit color interpolation for 2X rendering
- update framework

There is currently no way to do that, which i know off.

There have been fixes to the memcards about 1-2 months ago, i can't remember exactly when. There is also still a rare bug that when loading a game, the automapped memcard will not get loaded, but you get random garbage instead. I could not yet identify the reason for this, but you usually notice it ingame as the game cannot read any data from the c...

Also works here until ingame (selecting Quest mode).

Please check your settings or your image.

You can put a file "noreset.txt" in the same folder, so you can load different CDs. More info here: https://vampier.net/PSX/ For the hang i can take a look later. It's suspisous, because the game was tested a lot and nobody told before. Maybe it broke recently. Feel free to enter such bugs in github. If you attach a helpful savestate to a...

It's probably best to ask for that in another subforum, e.g.:
viewforum.php?f=33

It's not specific to the PSX core.
