Compression: PPSSPP .chd compression broken with CHDMAN use .cso
User Maddo on Discord reported: I wanted to point out that PSP compression to chd is currently buggy and there is some currently undefined behaviours with CHDs created using createcd instead of createdvd
PPSSPP Issue: https://github.com/hrydgard/ppsspp/issues/18798
Maddo suggested target .cso instead for PSP with maxcso maxcso
Anyhow as chd is bugging we should disable it
Also wrote: createcd leads to skipping animations and such, so yeah, chd work but absolutely use createdvd
Either way this will need an updated tool. The version of chdman we currently package doesn't support createdvd, and maxcso seems like a preferred format for PSP anyway.
Looks like it has changed with the lastest MAME versions as well according to the above issue on PPSSPP since the January update. So if we update chdman and use createdvd it should work.
I can confirm this to be the case, PPSSPP 1.17.1 works fine with chdman 0.262 and createdvd option. createcd makes a few animations skip, making the game feel stuttery. Reached out to the developer on discord and he confirmed that createdvd is bugfree and works as intended.
