    Hacking EZ-FLASH Junior TestFlight

    Perfectly working here, on a non-sufix GBC. For all of you having problems, copying the update to the SD is no enough, that only updates the kernel, for updating the FW (which is where the problem resides), you have to run Update_FW5.gb. Of course, that requires another working console...

    Hacking EZ-FLASH Junior TestFlight

    I noticed a small bug in the 1.04 menu. If I open a folder with a lot of subfolders (letters from A to Z for example), scroll down to the last item (Z), and pres the right button, the menu displays garbage for a moment and the hangs. The linked video illustrates what I am trying to explain.

    Hardware GBA Backlight! (AGB-001)

    Here you have the schematic and the board layout I used. They are in Eagle format. In case you use a 12V regulator like the one I used, I can assure you that isolating the 5V rail from the backlight power supply is absolutely mandatory, otherwise the current out of the regulator could damage the...

    Hardware GBA Backlight! (AGB-001)

    White tab screen + 40 pin motherboard + removal of R16, R17, C33, C54 and Q3 + wire from RECV to P2-VEE gives exactly the same quality as the original AGS-101, and is a very easy to implement mod. If someone have a white tab screen, and can't get a 32 pin board (like me when I did the fisrt mod)...

    Hardware GBA Backlight! (AGB-001)

    I'm afraid I can't help you. All the screens I tested were white tab ones. Maybe someone else can give you some advice about it. If you already have the screen, I guess you don't loose anything by giving it a try. If you do it, please tell us your results, so we all can learn a bit more about...

    Hardware GBA Backlight! (AGB-001)

    Type A screens are not fully compatible with 40 pin motherboards. Soldering the cable will give you a brighter backlight, but the colors will remain the same. Adjusting the pot won't change too much either. To make the screen compatible with the 40 pin board, you must do the following: 1. On...

    Hardware GBA Backlight! (AGB-001)

    Before cutting the trace, connect the screen and try it, to see everything works fine . If the screen lights up, that means it is powered trough the ribbon. After that, if you want a bit more brightness, proceed with cutting and soldering. The regulator is powered trough the 3.3v line, because...

    Hardware GBA Backlight! (AGB-001)

    Hi ServenIkhana. Yes, there are about 13.5V on the D1A pin, but after connecting the LCD backlight the voltage drops to 11V, because it cannot supply enough current. LEDs are non-linear devices, so altought it could be hard to believe, there is a big diference in brightness and current between...

    Hardware GBA Backlight! (AGB-001)

    Hi everyone. In first place I want to thank everyone who discovered the method for modding the AGB-001 screen, and the people who posted their results so other people can learn about their mistakes and their success. I also want to share my experience with these mods, in case anyone is...
