hm ok ^^
i'm sure i transfered a gameboy mario golf char to the n64 version. :>
i'll have to check if the tp-controller sends other access state values if the lesh-nus is powered high on it's output side.
maybe bridging to the 5v side works better. :D

Any thoughts?

both :D
someone told me, that mario golf pal was working for him and pokemon not...
so we have to figure out, if it's just a game-version issue or a technical one. ^^

today i added transferpak support in mupen64plus to get more debug abilities. :D

Slightly Off-topic, but would you be willing to modify a transfer pak and sell it to me?  :D
I'm a complete ignorant when it comes to modding hardware :(

I don't got a spare TP to sell. But I can modify one, if you ship it to me and pay the shipping cost back to you.

i really don't get it atm. stupid mario golf. ^^

what i have tried in between...
-> dumping the cartridge savegame/rom and boot it with an emulator -> working on the emulator, so there is no version conflict
-> holding the cartridge externally alive and switching the n64 off and on -> dumping works - mario golf not

mario golf europe checks for the europe gameboy game and the us for the us one,
there is even a msg at the status option, which tells you, if it doesn't like the cartridge
the savegame seems not to be region locked at all


beside that, i'm pretty sure i have already successfully dumped a character once, i even wrote it in the libgbpak thread. :D
and on irc someone told me, that mario golf is working for him and pokemon stadium not. :>

any ideas? :D

Did some more testing today with both the E and U rom.

I get this error when crossing the versions with eachother

[Wrong game]

And this when using matching versions

[No saved charactors]

hi,

i did some tests, so if you are getting the same ideas you don't have to test them again.

my idea was, that the tp is able to check if the cartridge is already powered or not.

so I searched the 5v plane for connections with the LESH-NUS and found out, that there are 3 connections.
i was hoping, that one of them is a sense pin, but it seams like they are just 3 vcc input pins, they are all connected inside the ic.
i lifted them and connected them to the 3.3v enable signal for the step up circuit, so they are only powered if the tp wants to power the cart, but nothing changed.


my next idea was, that it is checking for a reset state or something.

i powered the cartridge itself externally, set it to game mode, shut off the n64 and even reconnected the controller.
guess what.. it didn't work. ^^
(maybe i hold the les-nus state powered from the cartridge side)


i could monitor all tp comamnds with my modded mupen64 emulator and retry them on real hardware, to look for the diffs in the response packages.
but even if the real tp reacts in a different way, the solution would be still rom patching only. :/


i'm getting out of ideas, maybe i'm not the right person to dig into that any further. ^^
bailing out, you are on your own. good luck :D
