Here they are:
version using out (c),0  ( i.e. scc ED 71)

version using out (c),a (i.e. scc ED 79)

I use them with Manuel Pasos SCC Flash ROM and OPF and a real A1GT

For those who use only pure basic and disks, use bload and the loaderED7X.bin files

In the ED 71 version all the sprites are not correctly initialized
(16 filled bytes appears on the right side of the frames).

In the ED 79 version everything works fine.

I would say that on my A1GT TR out (c),0 acts like it were out (c),255.

In emulators (I tested open and blue msx) both versions work fine, thus none of them reflect this oddness.

Test and let me know!!


PS
I received two confirms for the finding above, on A1ST the behaviour seems the same as A1GT.

PPS
To end the game you need to find a switch "X" that is 3 rooms down and 4 rooms right from the place where you start.

PPS
In the ROM version, who ends the game will enter in SCC SFX player.
Just press keys 0,1,2,3,4 to hear the SFXs.

PPPS
The ROM intruder_scc now includes (without any order) 30 PCM sfxs, 29 from the original game Berzerk
Kill as many robots you can to hear them
(the player mode still works but you can select just the first 5 samples, sorry too lazy to fix)
