Nitro Engine example .nds file hangs on loading and gets "bad transfer direction" error. #1669

Open awmc000 opened 1 year ago

awmc000 commented 1 year ago

Very similar to this issue:

https://github.com/melonDS-emu/melonDS/issues/1116

I run the .nds file generated by this template, having also added a "nds_nflib" folder (Night Fox Lib), in which I built before building the Nitro Engine template:

https://github.com/AntonioND/nitro-engine/tree/master/examples/templates/using_nflib

When I run it in MelonDS, it loads, but never progresses past the message "Starting nitroFS..." printed to console.

Here is my shell output.

This doesn't have to do with Nitro Engine, but with the implementation of nitroFS and the card commands used to read from nitroFS in emulators. In case it helps:

devkitPro: https://github.com/devkitPro/libfilesystem/blob/88c191cece4fa17daa0ddd2c76eb92165161481d/source/nitrofs.c#L163-L176

BlocksDS: https://github.com/blocksds/libnds/blob/afd5996ca6a5cf5b8ee69cfe85240ddf4b462372/source/common/card.c#L131-L142

The implementation in BlocksDS has the fix to remove CARD_WR, so it doesn't cause that error, and it works in melonDS.
