@Xrider - look at pickit2 plus . Think its supported in that

Thanks my friend

Thanks pyroesp.

Which programmer did you use to program the pic16f18325? I have pickit2, but when I check the support list I think it is not the right way

Hello pyroesp,

Great Work !

Can you make a port to Attiny (25,45 or 85) AVR chip ? low cost, take low space and only 8 pins (PB0 -> PB5)
Thanks you

Xrider

Hello Logan Jones, If you need a STU for make a development or dump everything or transfert memory card to your PC with usb, i can sell a motherboard with STU + Modchip integrated (No dual bios look like the picture follow). Price : 40 Euros + Add shipping https://i89.servimg.com/u/f89/11/72/10/23/n...

no, my software don't have link to psxdev :D you make dump of your PIO CART, is not BIOS I 'm sure, it's dump of the eeprom programmed with your CD. For dump it, i have put directly the eeprom on the Minipro TL866 programmer. But if your software have not the link to psxdev, maybe the erase fonctio...

Yes, i have checked this last night. So crazy. Maybe an error in the software of megavolt85.
But it's ok, it's dev stuff.

I am probably the first tester
I hope megavolt85 will fix it.

I confirm the ID of the SST39VF040 it's "BF D7" test this BIOS Flasher_0.2.7z Thank you for your help megavolt85 I have tried it and now it recognizes my eeprom. I tried to burn the SCPH-7002 bios. it take a long time (30mns) to burn 512Ko. After that, not work (CSO and CS2 swapped = same thing). B...

Hello kHn,

Can you creat/add the official ROM of bios PS1 in your futur compilation please (i know, it's doenst work with acrion replay) ?

It's for this :
viewtopic.php?f=62&t=3457

It's possible to flash it with Overburn in expand.exe (thanks no$cash)

Thanks

I have try to burn it with expand.exe (thanks No$cash) with kHn compilation (thanks kHn) and it's work when : WE is connected to SWRO CE is connected to CS0. It's work look like the Action replay. I confirm the ID of the SST39VF040 it's "BF D7" I think about it's possible to flash the original bios ...

Nice job Armorant,
My first revison was look like your pcb, but i would like preserve the genuine bios and add au dual bios fonction, and for that, i have make the new pcb
I use the same eeprom, the SST39VF040

Thanks for your interest rama3,

I will make lot of test before sell it.

But i don't forget you rama3...
Please send me your postal adresse in PM

Hello, It's working (no tested yet with cd for reflash) : http://cyberscooter.free.fr/darius-saturn/flash-swap-bios/IMG_0970.jpeg http://cyberscooter.free.fr/darius-saturn/flash-swap-bios/IMG_0971.jpeg http://cyberscooter.free.fr/darius-saturn/flash-swap-bios/IMG_0972.jpeg http://cyberscooter.free.f...

If you can let me know when you have the boards I will quite happily buy a few.. I have some ST39 in hand in TSOP32 but they are 256k so would also need the chips. danhans42 When I have received the circuits, you will be the first to know. do you want a totally assembled card with a TSOP SST39VF040...

Hello danhans42. Thank you for your interest on my project. It is with pleasure that I will sell you two units at a reduced price if you can update NxFlash to be able to flash them. I wait my first PCB, it's will come in couple of weeks. Ideally though, I would like a PSone compatible version that a...

Hello, I just told you about my project PS1 bios exchange. I took a step in PCB design and physical testing on a PU-20 (Motherboard SCPH-7002) The tests are conclusants. Here are some photos: Mounting: http://cyberscooter.free.fr/psx-dev/IMG_0673.jpeg Bios No $ Psx http://cyberscooter.free.fr/psx-de...

Hello everybody, Just for information, is not a simple mm3 and FTDI. The FTDI is genuine part Look this picture : http://www.delta-island.com/partage-darius/stu-fullmod/IMG_0186.JPG It's the same mod of the picture but with no dual bios mod And in short time, Darius will release a new mod for PS1, w...

Fixit !

Thanks Rama3
