    Great news!

    I noticed on one of my EZJunior on the PCBs is written "EZGB 1320", and on the other one "EZGB 2120"

    are these different revisions?
    or can you tell me the difference?

    Couldn't you just take the SGB out of its plastic shell? It comes apart like any other SNES cartridge.

    We can not open it without proper screwdriver. And the unit is old and has bad contacts, so I don't know what new problems will arise when I take it apart.

    I just posted a new release of my RTC tests: https://github.com/aaaaaa123456789/rtc3test/releases/tag/v003

    It's giving mixed results on these new tests. Some of the writes' timings are OK, some are far off.
    I also noticed my cart's RTC is fast. The tick time is 996.9ms, i.e., it's fast by 0.31%. This might not seem like a lot, but it's a drift of over four minutes per day, so it adds up really fast. @EZ-Flash2 maybe check with the RTC chip manufacturer? This can't be right.

    It is not a game. I've written color GAMES on GB Boy Colour. They do not work. Some of them work, but mainly not. Plain gameboy games work.

    Then use real non-clone hardware and they all will work

    My RTC in the actual menu seems to have kept time perfectly fine, so it at least doesn't seem like it's the RTC chip? Which can then mean it's only the software?

    Mine goes out of sync after like an hour or two when powered off, but that might be the battery. The battery doesn't matter when the GBC is powered on, though.

    Are you also getting 996.9ms ticks? Do you see a different value if you run the test multiple times?

    This error should be caused by the quality deviation of the crystal oscillator. This can be avoided by replacing expensive, premium crystal oscillators with...

    The issue is that 0.31% is a massive deviation. If you had a watch that had a 0.31% drift (which corresponds to four and a half minutes per day), you'd throw it into the bin right away. And low-end watches are certainly not expensive...

    They are talking about the GB Boy color not the GameBoy Color.


    The GB Boy color is a cheap clone that works with official GB and GB color carts, but most Flash Carts dont
