well sometimes it was, dust would get in the cartridge slot, and even that had to be cleaned vacumed. but i guess thats a maintenance issue instead of a mechanical one. Also, the cartridge slot contact surfaces kinda get worn out after a while and cant read right sometimes. I guess modern consoles have the main problem of heat, because they run on multi ghz processors in such a tiny box/space. as opposed to consoles before which ran on 12 or so mhz. heck they didnt even need fans, just tiny heatsinks
