Did you try faster transfer rates, too? Ackerman mentioned reaching "71680 bps" on the SPI data lone (=144360 bps on the SPI clock line). So the upper limit might be near 144360 bps, or perhaps faster when removing the 100pF capacitors in the console. I really did not try any other speed,...

I've not tried that particular case. As long as it can send standard, non-inverted data on the data pins it should work with joymon.

Congratulations socram on the project. Regarding the serial usb converter, is a specific model of FTDI chip required, with line inversion, or similar, or does any of them work? No line inversion required - regular UART with 3.3V for logical 1 and 0V for logical 0. The outputs are actually inverted ...

I know, but I didn't want to drill my console to put a serial connector!

Available here: https://github.com/socram8888/joymon. It's still quite rough, but does work.

So debugging some quirky behaviour in tonyhax , and the classic process of copying the executable to a USB, then loading onto a PS2, running uLaunchELF, then copying onto the PS1 memory card, then booting the console, was getting old really fast. A sensible person would've probably used something li...

I assume that the information listed on TonyHax Compatibility is a misprint. Yeah it was. I had read that vC0 disc controllers were not compatible and somehow misunderstood the documentation, thinking that SCPH-1000 were NTSC-U and ran on that version. I think all NTSC-U consoles should be compatib...

Do any of you know if there is any way of triggering the AP on no$psx? Because so far I'm only adding support for games people can try on real hardware and report back.

By the way, in your file https://github.com/socram8888/tonyhax/blob/master/cdrom.c, you shouldn't delay the system by a simple for loop. Instead, use the VBLANK interrupt. NOTE: 30 may not be enough, so change the value as needed. I pretty much can't at the moment. In order to keep the code as smal...

You went with one of the hard ones haha. Cool Boarders has a checksum over the entire save contents: https://github.com/socram8888/tonyhax/blob/master/fix-cb4-checksum.sh Crash Bandicoot 2/3 do too (https://github.com/socram8888/tonyhax/blob/master/fix-crash-checksum.sh). The rest of the supported o...

Just a quick update. The title is a bit outdated. tonyhax since today (v1.2) works with all the following games: Brunswick Circuit Pro Bowling (NTSC-U) (SLUS-00571) Brunswick Circuit Pro Bowling (PAL-E) (SLES-01376) Brunswick Circuit Pro Bowling 2 (NTSC-U) (SLUS-00856) Brunswick Circuit Pro Bowling ...

I can make a small program which will write the save game data to a Memory Card. I'll try and do it when I have some spare time. I'll have it read the save from the disc as a separate file and not from within the PS-EXE as a machine code so updates can be overwritten by using a program such as CDMa...

That's pretty damn cool. I wonder if it'd be feasible to alter the game code to include more slots. I'll check it.

Is it okay if I create a burnable PSX disc that contain your Tonyhax files? My idea is to modify one of those PlayStation Underground demo CDs and bundle your Tonyhax files. There's a section on those discs called "Download Station" which lets users download memory card saves to a PS1 mem...

... It should run totally fine with swapping. Though with how cheap they are I'd probably just get one of the supported games (THPS2, 3 or 4, or Brunswick Circuit Pro Bowling 1/2). Regarding the PS2, the documentation from no$psx says it's not compatible, but I've got three reports saying it works ...

Nicely little exploit! Unfortunately it won't run all games though. You will run into some problems when you re-setup the kernel as some are very picky about how it's configured. In theory, there should be heaps of other games which can run the exploit too (not just Tony Hawk 2 and 3) which widens ...

Hello! Socram here. It's my first time doing any development on the PS1, but I've done some work on other consoles, such as breaking the amiibo's cryptography. I'm here to present you all a small project I've been working for the past month. I have a boxed, nearly mint PSone SCPH-102 that I really d...
