multiMAN 04.19.06 UPD Released

Following up on the previous release, today developer deanK updates multiMAN to version 04.19.06 with the following changes below.

Changelog:

• Added support for PSXEMU/PSXNETEMU emulator selection for PS1 BIN+CUE backups (Press [Triangle] -> Game Settings)
• When using PSX NETEMU option the disc backups must be in MODE1 or MODE2 / 2352 (or more) bytes sector
• Multi-disc games are not supported in this initial PS1_NETEMU-support version

The default launch mode for PS1 file backups is “AUTO” = PSX EMU. Some games may require or look/perform better when using PSX NETEMU. The patched versions were tested on 4.30 and 4.21, but hopefully 3.41 and 3.55 versions will work too.

This method is similar to the ps1_emu.self patching and doesn’t affect other apps nor uses system calls which make break other apps.
