(PS1) Mayumi 4.0 12F683, 12F675, 12F629

http://dl.consolecopyworld.com/?id=psx&file=patch-it!zip

Here's a region patcher I found with a quick Google search. You can also use "Import Player".

You're welcome!! Glad some people can appreciate the time I took into porting + testing it. You used the 12F629 version I assume?

Yes, I used 12F629 in SOIC-8(SOP8) package, but I am sure it will also wors well with DIP-8 version.
It might be a good idea to start to create a compatibility list of supporting revisions (I have them A LOT, many kind of J and E revisions, 1000, 3000(PU-7), 3500(also with PU-7 - if my memory don't cheat me), 5000, 5500, 7000, 7500, 9000, 1002, 102). But I have to wait about a mounth when I will get my 12F629 from China. Today I bought the last two pieces of 12F629 from local store and they were pretty expensive (x3 price vs price from Aliexpress). So, when time comes I will be glad to share my results.

SCPH-5500(J)-Not confirmed (Spinning a little even if it is a licensed disk and no more, need to resolder)
SCPH-7000(J)-Great
SCPH-9000(J)-Great

 

Awesome, please do.
When there's more results then I would make a chart for it. Not too much to go on now, but also if it's not working for someone there's a chance it could be a mistake/issue on their end as opposed to with the code.

 

Very thanks for publishers to reply information, convert area of the software I have found, in 0 and 3 at the end of the PSX inter-district game can run normally

 

i just find dirty cheap psx 7502 pal unmoded. im gona try mayumi 4.0 with pic 12f683 also im gona buy some parts at near electronic shop to build this http://assemblergames.com/l/threads/tutorial-making-your-own-ps1-modchips.55904/

 

Hello all! Great thread!!! The chip works flawlessly. Could it be possible to port 750x.hex to 12F629? Would like to build the old usb "neokey" for my good old ps2.

 

Glad it worked for you. Could you share what console you used it on?

What's 750x.hex ? I could look into it, but have no way of testing it.

 

Used on 1001 and 9001... About the 750x.hex is an old psx hex file for the 7502 models that is also used in the ps2 for the "neokey" the old usb modchip that required only one internal jumper. Used for direct boot of psx backups. Ps2 backups required a gameshark or other original boot disc. With this I can instal FreeMCBoot on the ps2 from the disc. After that is done then the chip is no longer needed although it could still be used for the psx backups which do not load directly on freemcboot and have to be played via emulator and external hard disc so it would be the best of both worlds, boot ps2 backups directly with freemcboot and boot psx backups directly with this modchip. I'll do all the testing you need... LOL...

I found the hex and the asm. Hope it helps...

re

yea i remember that. is the first modchip for ps2. im also interested for that. a freemcboot from memory card or from hdd for ps2 games. and a chip only for psx backups is that possible for 5000x ps2 series or even the slimline7700x series?? if yes could you please give a diagram??? thanks in advance

 

I think the chip only works up to v4 consoles. As for FreeMCBoot it works on consoles up to date code 8B so I guess your best bet is to buy a memory card with fmcb pre installed from ebay, they run for about 5 to 8 bucks.

 

mm thats bad iwas interested for the psx backups part. my fat ps2 5000x have already the fmcb.

 

Only way I see is installing an internal modchip on the slim and some of those require the "Romeo" mod. I feel like I've traveled back in time to my late teens/early 20's LOL... Unless the usb chip can be installed on the 5000x which I'm still not sure those are the options. MODBO chips are dirt cheap but is a 20 wire install...

 

I do believe that the "Lucifer" solderless will work on your V10 (5000x) Just saw one on ebay.

 

thanks I willook for it

 

Mord.Fustang will any of those files help you out? If not tell me what you need and I'll search.

 

Check your PM Apexseal.

 

sadly i found nothing on Lucifer modchip

 

Wait, is this now about chips that allow PSX backups on PS2 by chance? I would *love* to have that capability.
Does anyone know if simple PIC modchips can trick PS2s? Also what about PAL bios protection (as used in the PSOne models, which require bios patching on PAL machines.)?

 

i know for sure that neokey can do psx backups on ps2 and keep homebrew intact. but all diagrams are up to ps2 v4

 

Ok I guess some of you guys are not as old as me LOL... Neokey was one of the first modchips for PS2, it used the 750x hex from the PSX (this was about 16 years ago), all that was needed was a jumper wire soldered inside then insert the usb device. It only works up to v7 I believe (seen some V7 diagrams). It works this way after installed: Turn it on (it had a switch and led but that is optional), eject the tray, insert the PSX backup, hit reset to close the tray and that's it, direct boot. (PS2 backup games had to be loaded via gameshark). So basically the idea now is to direct boot PSX games like before and still be able to play PS2 backups via FMCB (the psx emu is just not good although it was a great effort).
