Nah. He Made Two Mistakes. Didn't Want To Point Them Out.

Yeah, they are. The typical way of connecting a backlight to the unregulated power supply is to connect the positive side lead to the 1k resistor near the top, on the side closest to the ribbon cable. If you don't care about the backlight, you can remove the resistor and solder the wire through the hole. Negative still goes to ground.

Of course, with this method, the backlight intensity varies with the battery voltage, and maybe the 6V from four fresh batteries may be slightly higher than what is healthy for the panel.

HF vibrato/pitch slides are not tied to ticks. Non-HF vibrato pitch slides are tied to ticks, which may be limiting in some instances, and useful in others because of the predictability.

This raises the question if it's a good idea to connect the backlight to the regulated power output rather than directly to the batteries (after the power switch). Yes, you get a more even power level, but the screen goes dim more quickly and you might throw away perfectly good batteries. On the other hand, the screen also goes dimmer as the batteries run dry. So it may be all the same in the end.

Are the batteries fresh? Are all the battery contacts clean? Where are you tapping the power for the backlight?

Startup.gb only works with software especially written and compiled for it. It absolutely cannot work with existing ROMs. Just forget about it.

The point of the Polish student design is to replicate the design of a Nintendo MBC5 cartridge, but with a flash ROM chip instead of a read only ROM chip. Since it's just using an actual MBC5 control chip, it's limited in that regard to what original cartridges could do. Since it has a flash chip that is directly accessible from the GB CPU, you *could* make a multi ROM system where you merge several ROMs, and a piece of code that writes a new ROM to the bottom area of the flash chip, which would enable different programs to coexist. But there are several problems with this approach:
* Flash chip wear from repeated writes to flash memory.
* You risk "bricking" the cartridge every time you select a new ROM, if the power goes out or something else unexpected happens. (By bricking I mean that the cartridge needs to be rewritten from the computer.)
* The total flash memory size as well as the time it would take to load a new ROM would make this pretty useless for anything but rather small ROMs.
* The software required for this would have to modify the ROMs, which might be a bit tricky.

Hmm, but if anyone actually wants me to try to make this software...

YES AND THIS HAS ALREADY BEEN ANSWERED HERE AND HERE AND ALSO WRITING ALL CAPS MAKES IT LOOK LIKE YOU'RE SCREAMING EVEN IF YOU'RE QUOTING SOMEONE!

12ianma, the CPU position is slightly off, and I'm not completely convinced all the joints are clean and non-shorted. Was the resoldering done with an iron or hot air workstation?

Another thing, don't throw away the GB CPUs or SGB motherboards. They won't work together right away, because the SNES side of things will wait from certain boot commands. However, I've been able to send these commands from a program running on a flash cartridge, so maybe the combination SGB board/GB CPU might be of some use to someone, somewhere.

As far as I can tell, everything is correct except that the PS2 socket connections are mirrored. Furthermore, you may have destroyed the keyboard permanently because mirroring the plug means that you have reversed the polarity of the power supply to the keyboard.

First sanity test: Does the keyboard blink when you power on the Gameboy? Normally it should, and if it doesn't, your problem is probably that the keyboard doesn't get power.
