so I got my hands on this console, it has a matrix infinity modchip installed, disc drive is FUBAR. I can get my hands on (or rather, make) a MX4SIO adapter, and also have a fake 64MB ps2 memory card
With matrix infinity when you boot holding triangle, it will execute the "matrix manager " ELF , that can be replaced with any other app
I need to double check the path of it. If you have any other PS2 to manage the memory card, the fake 64 would be just fine to boot with matrix chip as long as you can put the file in the right place
yes, that's DEV1 on the modchip. i have no way to drop the ELF on that memory card since i don't have freemcboot installed or a working cd drive to boot from, but i can make an mx4sio if needed.
