I tested it out. I get an error that says to make sure the ROM is in the same folder as the music. It is.😮‍💨 I assume it just doesn't work with the #SD2SNES That's a shame. It works fine in an emulator.
This is hands down the best #ROMhack I have seen in a while. Dude, ported #Metroid on the #NES to the #SNES. He also added MSU-1 support with near CD quality orchestra soundtrack. He added some quality of life improvements such as a map etc. This is a must play if you have a #SD2SNES or #FXPakPro flashcarts. It also works with the latest version of #SNES9X.

Infidelity over on Twitter has posted the latest revision (E) of his port of #TheLegendofZelda from the NES to the #SNES. This port has #MSU1 support that adds full orchestra music to the game if you are using it on an #SD2SNES or a #FXPakPro. #retrogaming https://twitter.com/infidelity_nes/status/1679111360615964674?s=20

Got shipping notification for my Analogue #SuperNT and honestly wasn’t expecting it for at least another half year, given how long it took to get my Analogue Pocket. It’ll be fun to have a way to play my #sd2snes on a modern tv
Been working on an automatic item tracker for the ALttP randomizer when using the #SD2SNES. Finally got it to the point where I think it might be useful for other people, even though it’s definitely not complete yet: https://github.com/jhelwig/sd2snes-lttp-rando-tracker #ALttPR
