I'm working on ROM/IPL replacement (for linux o/c, NOT for games),
something like tmbinc has done. I think I will try to develop a little
circuit with flash rom on board, but for now I'd like to use tmbinc's
solution: a memory card with the code. I know Nintendo cards are locked,
and it is not yet known (in public) how to unlock them. I don't have a
Datel Action Replay card, which does not need unlocking, but a cheap =
Piranha card, and I would like to investigate whether this one is locked
I wrote a little program which reads the ID from the mem card, and
prints to screen. When I use it, it prints 00 00 00 10 (251 blocks
card). When I remove the card, it reads ff ff ff ff, and when I reinsert
it, it reads 00 00 00 00. Since this is different from 00 00 00 10, I
would say: this card does have a locking mechanism. Now, would someone
who has a Action Replay spent 5 minutes to repeat this experiment?
The dol file can be found at
I have a bunch of memcards. I boot PSO with a 8Mb Big Ben card in slot A.
Here are my findings:
1. after booting 00 00 00 08
2. when no card in slot A always FF FF FF FF
3. after reinserting the Big Ben 00 00 00 00
4. with any of my two Thrustmasters 59 blocks 00 00 00 00
5. with a 2043 blocks (128Mb) no name 00 00 00 00
6. with an Action Replay FF FF FF FF
7. with a original Nintendo 59 blocks FF FF FF FF
Now, I'd say the AR and Nintendo are locked and the others unlocked ?
Btw: that is a nice milling machine :)

First of all, thanks for your cooperation
>Now, I'd say the AR and Nintendo are locked and the others unlocked ?
That is really strange. According to
tmbinc(http://debugmo.de/gc/gc.html) the AR does not contain any
locking. It seems obvious that the Nintendo ones do.
