There are different MEGA65 models out there in the wild, so make sure you choose the right core variant for your hardware.
If your MEGA65 was manufactured before 2024, then choose
zxuno-v1.2-r3.cor otherwise choose zxuno-v1.2-r6.cor.
We are supporting these MEGA65 models: R3/R3A, R4, R5 and R6. Use
the following table to ensure that you select and flash the correct .cor
from the ZIP file.
| MEGA65 model | Years | File name | Comment |
|---|---|---|---|
| R2 | 2019-2020 | r2zxu08.cor | R2 is a very rare pre-series model, only 20 of them were built. We are not supporting the R2 any more, but you can still use Version 0.8 of the ZX-Uno core on R2: https://github.com/sy2002/zxuno4mega65/tree/master/bin/Version%200.8/R2 |
| R3/R3A | 2020-2023 | zxuno-v1.2-r3.cor | R3 is the "DevKit" (100 were built) and R3A are batches 1 and 2. If your MEGA65 was manufactured before 2024 then you have an R3 or R3A machine. |
