Fix: Use standard MC driver type for mcInit

I changed the `mcInit` call in the `InitPS2()` function in `main.c`
from `mcInit(MC_TYPE_XMC)` to `mcInit(MC_TYPE_MC)`.

Using `MC_TYPE_MC` (standard memory card driver) instead of
`MC_TYPE_XMC` (eXtended memory card driver) may improve compatibility
with a wider range of memory cards or in certain PS2SDK environments.

This change is an attempt to resolve the "No MC detected" error
(error code 1 from `install()`) that occurs after `mcGetInfo` fails.
If the eXtended driver type was causing issues with card detection or
initialization, switching to the standard type might alleviate the problem.
