Hi @abraX-Xious ,
the first point, the MEGAmaze is a demo. we know that it tends to hang from time to time. (we're still investigating why)
Regarding the commando tune beeing too fast, it might be, that your machine is set to NTSC. Try holding ALT key, while powering MEGA65 and change the Default video mode over there.
You can also change the video mode in the Freezer menu. Once your MEGA65 has booted press and hold RESTORE fore about 0.5s this enters the Freezer and press V over there to change video mode.
To check if your MEGA65 is behaving normaly, try the following:
Hold the MEGA key (bottom left) pressed while switching MEGA65 on. This boots the MEGA65 C64 mode. once in C64 mode try to LOAD"$",8 and LIST
is the MEGA65 accessing the disc image of the SD normally ?
Please report and thanks !
