My MB-6582 stopped working and it's all nILS' fault...

I was playing some SID files that nILS sent me, using ASID XP and my MB-6582 when the MB-6582 stopped playing SID files (it happens a lot). So I reboot the MB-6582 and it started acting weird, some LEDs that shouldn't be on were lit at less than full brightness, and some button presses would jump to completely different menu pages. nILS' SID files had some kind of C64 opcode virus that infected my master PIC, so I reburned it with the bootloader and uploaded MIOS and MB-SID app again but the problems are still there... maybe the virus has moved now and is jumping around the PCB... do I have to now desolder all the components and solder new ones? How do I get rid of this nasty virus now? WTF IS WRONG WITH YOU NILS!!!!!!!!!!!! How could you send me SID files with a virus and fry my MB-6582 just before I run 6582A SID MEGA-SALE #7???????????? ARGHGHGHG GRRRRRR >:( >:( >:( >:( >:( >:( >:( >:( >:(

nILS' SID files had some kind of C64 opcode virus that infected my master PIC, so I reburned it with the bootloader and uploaded MIOS and MB-SID app again but the problems are still there...

This is so deja vu...

Apparantely you forgot to solder D1 of the core module, which acts as a protection diode against illegal opcodes received from the MIDI interface. Take care that the diodes between J15:D2/3 are stuffed on all cores as well, otherwise the opcodes could be forwarded to the slaves via CAN bus, and they will be sent back on the next power-on cycle so that the master will be infected again after a fresh MIOS and MBSID installation.

Best Regards, Thorsten.
