    Hardware SuperChis Prime: How I Fixed the SuperCard SD's Flaws on a Budget

    In order to make sure the batteries were fully charged, I contacted the battery factory. If they didn't lie to me, all the batteries should be freshly produced. 100%!

    Hardware SuperChis Prime: How I Fixed the SuperCard SD's Flaws on a Budget

    I have some data about battery life, but there is no conclusion yet. We can collect feedback in ten years, hahaha. After testing, the current of SRAM in sleep mode is 70 ~ 100nA, which means almost no loss, we only need to consider the self-discharge of the battery.

    Thank you very much for your review! I also recommend turning off DirectSaving unless the battery is dead. The SuperChis sold on AliExpress use my compiled SuperFW, which was compiled before version 0.19 and has not been updated. This will cause some trouble, and I will solve this problem in...

    $41 is too expensive, I recommend using SRAM and battery. This is a budget flashcart after all..

    The 03 motherboard without aging is more stable than the 02 1769795269 Maybe around 2000

    I will, we're doing more testing to make sure we can actually fix the problem. At present, we have solved the problem of failure in the flash process, but there are still some instability issues in the game. The good news is that I found some NOR Flash, they are slower but low power consumption...

    [WIP] SuperChis —— Open source GBA TF Flashcart

    Maybe the sound comes from the GBA's inductor? Or maybe both. The components used on the SuperChis make it difficult to make noise, in theory.

    [WIP] SuperChis —— Open source GBA TF Flashcart

    This is normal and erasing the NOR will cause power fluctuations. :D It's not from the cart, it's just the speakers getting random fluctuations. This is why some aging GBA and 02 motherboards cannot use SuperChis, which consumes too much power when erasing. But when playing games, its power...

    Yeah. ChisFamily is the best choice. All you need is an SD Card.

    Not all 02 motherboards have issues, but often occur on 02 motherboards. For example, the ROM cannot be loaded, or the screen goes black.

    We are designing an open-source GBA power enhancement solution. Some compatibility issues can be resolved.

    Hahaha, this should be the simulator designed by Davidgf for SuperChis, the real SuperChis are not that fast. 1769564516 What do you think? Do you like SuperChis?

    Because there is no "faster SDRAM", it is impossible(hard) to find 256Mbit SDRAM that supports CL=1. It needs to be replaced with something like PSRAM.

    Yeah. We have 992Mbit of NOR space. About 5 to 10 games. There is no B mode. 1769404014 Hello! We found the problem with the 02 motherboard. The reason is that the power supply is insufficient and the common S29GL01GS cannot be used. JS28F00AM29EWH needs to be used, at the cost of longer...
