I pretty much can't at the moment. In order to keep the code as small as possible I am not using the official libraries and afaik VSync isn't present as a BIOS call. Correct me if I'm wrong, please. No need to use BIOS calls. Interrupt register is memory mapped, you can read and acknowledge it by r...

Excellent work LameGuy64, very impressive
I really appreciate that you shared the source for your SDK on GitHub.

No I haven't. It's under "Download and install toolchain" section.
But you have to scroll to reveal the entire code, maybe that's throwing you off...

Yes, however that repo is outdated. The newest PSXSDK is 20180115. I could make a new repository with the current version but there are two problems with that approach. 1. It's not my project, 2. If Tails keeps updating his SDK then we will have code discrepancy. So I would really like to have an of...

Thanks. Yeah, it's a pain sometimes to get everything working. I actually also wanted to add macOS to the list but I'm having trouble compiling PSXSDK's tools for the host OS. Compiler seems to be stricter and what would otherwise be warnings it treats as errors. But it's OK, those errors/warnings n...

I updated the guide. Now for both Windows and Linux (Ubuntu) and with the latest binutils and gcc.

Was it you who jumped all those fuses or did you get it in that shape? What a mess... :( Fuses blow for a reason. You need to remove all those wires and reinstall working fuses. And it looks like you jumped a capacitor in one of the images. Might just be the thing that is killing (killed) it as that...

I have been following the news around PlayStation Classic and it seems like hardware is of good quality but software is shoddy (PCSX ReARMed, lack of options, slower PAL titles, crappy interface, etc). Once it's hacked I believe it will be a pretty neat system to own. Would be cool to have Retroarch...

I analyzed differences between my dumper and NexTro and came to conclusion that it's related to _96_init() function which initializes CD-ROM system and is called by the PSXSDK's PSX_Init(). In newer versions of SDK Tails92 added PSX_InitEx() which allows coder to specify various flags, one of them s...

/WE should be Write Enable so just use a pullup resistor.

Oooohhhh I get it now. Someone performed a PAL color mod on the consoles (to get PAL60 in NTSC games). When you removed mods (modchip, oscillator and bridges) you also removed a bridge which connected that trace to GND. SCPH-1002 and SCPH-9002 boards differ so for 9002 removing bridge and connecting...

Hm... That image looks like it's missing a red channel but the background would be aqua, not white. Could it be that your phone fixed white balance? Here is my recreation. sony logo.png Is there anything strange around IC501? And do you have an RGB cable to test the RGB output to see if it's fine?

I could write a separate guide for that if anyone is interested, as this one was intended to be just using an FTDI as it requires no extra parts other than a cable.

Definitely. Guides are always appreciated

Yes, that cable has FTDI chip but also a ZT213 which converts TTL signals given by the FTDI to RS232. If you were to remove ZT213 or add MAX232 then yes, you can use the cable. Otherwise no. Just check out the name of that cable: YIDAMA-TONGLE for Win 8, Win 10, Android, Mac, FT232+ZT213 , USB to RJ...

I believe those are RS232 cables and not TTL. I remember from my high school days in Cisco course we used cables with DB9 to RJ45 connectors which those cables you linked are emulating. In short, you will fry your PS1 if you connect it without MAX232 IC. Edit: Haha, I still have one of those lying a...

Hm, that's a great observation Danhans42 but I don't think that's the issue if NexTro is working. Apart from a different size defined in header all applications (working and non working) have the same initial load address. Must be something else... Screen Shot 2018-11-24 at 01.12.03.png I wonder if ...

Very cool.

Older versions were made using blade's libs while 2.6 was made using PSXSDK. Might be related.

Can you try launching something form this list? Those applications are all programmed using PSXSDK.

Impressive work LameGuy. You probably already know about this but if not it might be useful. The Playstation had this oddball 512×240 video mode that everyone else ignored, it wasn’t standard (320×240) and ate up video memory others wanted for textures. But it looked SHARP and we found the machine w...

No. There is a copy protection mechanism in place to battle piracy. You need a modchip.
