We might have a lead on why Jackie Chan could be freezing randomly, so we'll wait a bit longer to see if we can get that fixed in this update.
A great decision! The more important the update, the more important it is NOT TO rush things.

BTW, what about FFVII and Resident Evil 2-3? I don't see any mention of them.

They should be fixed based off of the other fixes, but if people still have trouble with them we'll take another look again. I remember I tried Resident Evil 2 and I couldn't get it to freeze, so it'll be up to the community to see what they find.

I see, so they seem fixed to you guys, but more testing is needed to make sure?

Yeah, more testing is needed by the public.

The new Midboot option in the EXTDSP settings is for CyberSpeed.

Fastboot Changes:

Code: Select all

  - Completely re-written from scratch in assembler again.
  - We now use the pre-boot method (running entirely from ROM) which is executed directly from the BIOS.
  - Boot times have been drastically reduced.
  - "CyberSpeed" now works.

Only for CyberSpeed? FFVII is assumed to work with the standard EXTDSP setting?

We assume FFVII had issues because of seek timings, so it should be fixed based off of the other fixes we implemented for the other games. It should work fine with the current EXTDSP settings like before.

It seems like you've created Midboot just for CyberSpeed. That's called dedication!

Hey Matt, I'm looking forward to that update. However I don't see anything regarding a "remember last played disc" option. Will it be in the next update or in a following one ?
SCPH-1002 w/ switchboard, Stealth 2.8a chip, double OSC Mod, PSone laser assembly, SCPH-7502 power supply mod.

We haven't added writing to the SD Card yet, so that option isn't available at the moment. We've been focusing on game compatibility which is a more important issue. We'll get around to doing this feature later on :)

I can't wait for the secret of Jackie Chan to be revealed.

Great update, looks like you fixed all the games I was having issues with :)

Looking forward to trying it out, Thanks!

RE: fast boot, I've never enabled it but would you say it's free from issues now with the rewrite? Or might there still be some compatibility issues?

Are the current limits like the max files in the root of the SD card being tracked somewhere? I found a thread that mentioned this possibly getting bumped up from 512 in a future update. Is that still on the roadmap somewhere? Would it make sense to add whatever the current limit is as an FAQ item?

The new Fastboot should be stable, but if it isn't just let us know and we'll sort out a patch. We test these things as best as we can, but sometimes someone has a particular PlayStation that runs into issue (the previous versions of Fastboot had issues I remember until we patched it).

Yeah we're tracking the 512 limit issue internally in our private database. Sure, we'll add it to the FAQ :)

So boot time in general will be a bit faster even when not using fastboot, or did I misunderstand? I'm the type that has to have that cool Sony splash screen (and also avoid potential issues with fastboot).

In any case, nice work on this upcoming update. After compatibility fixes the next feature I'm looking forward to the most is last game played, so it's great to hear it's in the pipeline.

It will be slightly faster either using or not using fastboot.

Attempting to disassemble "Jackie Chan: Stuntmaster [NTSC]" in Gihdra in order to reverse the function that's causing issues to raw C code. We're slowly getting closer :)

There's a problem though. It's not disassembling correctly as seen in NO$PSX.

Disassemblers for PS1 were always a headache. Did you try Munch?

Aside of the new updates listed, has the issue with the "audio music not working" when connecting the PSIO to a laptop to run games been fixed yet?

Also, has the "amount of games allowed on sd card" been increased yet? ...I think currently it's 512
