    Hey i recently got an ez Omega,
    I was wondering if there was any way of having it show a battery percentage of what the battery is currently on or even just a timer to show how long it has currently been on for (like an uptime measurement).

    No. There is not a way.

    For the GBA or for the battery in the Omega?

    I am guessing the former.

    Short version. No, and obviously GBA mode on the DS is still GBA mode and it was the DSi before we got proper measurement anyway.

    Uptime is more doable. Two main approaches being if you have real time clock on your cart then should be easy enough to ping it every so often and note that. Then either do something like the in game readers/menus (I know they were mostly for the DS but something could be done for the GBA) or fiddle with savestates.

    Longer version. You can bump the power draw up and there is usually a little light somewhere that will indicate low voltage.
    If they really wanted they could find a way to add a small routine that would take over, run minimal current draw and then bump it up (add sound, slam the CPU, do all the DMA reads, if you can do something with the cart's own FPGA or whatever to increase draw then fantastic...) to get it to pop up the voltage on the low side low light and calibrate it accordingly either for that system or more general ones (harder there as a spanking new SP battery is probably different to a "under perfect conditions on an original cart this decade or more old knockoff battery"). Probably would be hard to do for a fully charged battery but that would also be information.

    This is all a lot of work for "I know I am going to have to charge this if I play for more than about 6 hours".

    Yeah I was assuming that it would be at least possible using the real time clock and maybe even go a little bit further to start saving and recording the values for uptime to then get an average value for your gba/ds. From there it could compare the current uptime to the average maximum to give a very rough estimate of battery percentage/how long left you have.

    As far as I'm aware the Ezflash has an uptime clock right?

    Also I'm getting around 2/3 hours of battery life lol
