ISO Loader 0.8.x Beta + preview of DreamShell v4.0 RC 5

[SWAT]

I updated KallistiOS to latest and updated GCC to 13.2. Did a complete rebuild and made a test release: https://github.com/DC-SWAT/DreamShell/re...0.0RC5-T27
Also in this archive I put debug versions of core and iso loader firmware (in "debug" directory of isoldr).
So anybody can run with logging. But in some cases, logging levels will need to be adjusted to understand the reason.
When using debug loaders, you will often have to change the settings, since they take up more memory.
Serial baud rate is 115200.
