Here's my issue:
I can either play with USBLoaderGX set to Hermes CIos 223 and the game will play fine with a standard SD card with DLC..
If I switch USBLoaderGX to Ios 249, this makes the game SDHC compatible, but doesn't detect my instruments...
I want it to detect my instruments AND play with my 8 GB SDHC card..
UPDATE:
If you want to use USB Loader GX and have use of SDHC cards AND have instruments show up you need:
IOS 223 38 merged with 60
This enables both...
If you have IOS 249 base 57, and you don't have IOS 223 base 38 merged with 60, you need to downgrade IOS 249 to Rev 17, then use HERMES V 4.0 and choose custom IOS 223 base 38 with 60.
Then you can upgrade your 249 IOS back to rev 20 base 57..
Hope this helps!!
