El juego funciona muy bien!

If we consider that the Oric's ground is the referential, the psu produces -4v and +5v: the total voltage is 9v, then it is dangerous to connects the both wires like an independant power supply, it will produce a shortcut. However, if only one wire (+5v) is used to feed the Scart plug, that could wo...

Maybe this one

Exactly.

The chip is a 27128 UVPROM with a 16k memory, in this case the Erebus don't work, you must burn an other UVPROM with a ROMDIS pin compatible.

I agree with Dbug, there may be a UVPROM instead of the ROM in the Oric.
NB: The pin used by Erebus is /ROMDIS.

Without SDCard, Erebus will try to send a "0" SPI code several times without answer, and finally the computer will give a "MEMORY ERROR" message. With a SDCard without TAP files, the computer will erase the screen and will give a "READY" message. If all this happens, that mean that Erebus is ok and ...

Did you try Erebus without SDcard?

it works with a 512Mb card, I have never tried with a smaller memory, it is necessary to format the SDcard in FAT16, some smartphones do format in FAT32 even if there is a low capacity in the SDcard.

Maybe the sacrifice of the FNCT key?

Incredible library! I thank Dbug and all the contributors. All that's missing is the old bearded knight with a heavy sword guarding the entrance ...

You must put your memory chip under U.V light, the exposure will erase the memory.

Maybe there is an Uvprom chip inside instead a genuine Rom memory.

With colors !
Impressive !
