(sdl) Picodrive crashes when loading chd content #84

Closed orbea closed 3 years ago

orbea commented 6 years ago

OS: Slackware64-current Picodrive: 079bc1 gcc-7.3.0

When trying to load chd files of segacd games that where created from redump bin/cue files Picodrive will crash. The bin/cue files work in Picodrive and the chd file works in Genesis-Plus-GX which uses libchdr.

However the libretro core does not crash and will only show a black screen while the RetroArch menu is still responsive.

Ideally Picodrive should at least fail safely and at best should also support chd files with libchdr.
