[BUG] - Can't import a soundfont on rg35xx+

[r4dian]

• Platform : RG35XXPLUS
• Build: LGPT-RG35XXPLUS-1.4.2

Using the GeneralUser GS v1.471.sf2 from here, I try to add it to a Piggy song.

It doesn't appear in the sample dialogue on an Instrument page, either in /mnt/mmc/Roms/APPS/lgpt/samplelib nor /mnt/mmc/Roms/APPS/lgpt/{SONGNAME}/samples/

Does the soundfont need to have a specific filename too, or is there a different method to import it to a song than for a sample ? According to the table on the Readme of this repo it should be possible to use one.

Thank you for filing a detailed report.
Soundfonts are currently unsupported on that platform due to 64bit incompatibility.

Feature request rather than than a bug then - assuming the library used for sf2 support gets updated 🤞 ...

Feel free to take it on, the library was created in the 16 bit era ;D

I had a look into this, and managed to make a PoC for a fix locally, which I've been able to run (and successfully test) on my RG34XX SP.

The problem is due to how the soundfont library stores pointers (as 32 bit words), which cause problems when you use it on a system with 64 bit pointers.

I'll raise a PR when I find some time soon, hopefully this weekend.

Attached is a folder containing all you should need to verify for yourself :)

Works for me. Thank you both!
