+I just have a lot of Attiny13a and normal firmware for them was not.
+ Modavr does not support stealth, and does not launch copies from NTSC disks on the slime.
+ Then I came across the American firmware PsNee. It can patch bios slimki for NTSC disks.
+ But it did not support Attiny13a (it exceeded the size and used the flash.h not supported in Attiny13a).
+ Plus, the firmware itself was a compilation of different authors and contained a lot of garbage occupying a precious place.
+ Also there were glitches with a fast disk change. I corrected and optimized the code well and added support for Attiny13a.
+ That's basically it :)
+ Before the firmware, pay attention to define and the function inject_SCEx (). In the comments all are indicated.
