How to overclock your gameboy color.

I actually found a way to switch speeds using my socket method.
When the gameboy is on using the new crystal, take it out. The original crystal will kick in and you can play in normal speed. No to switch back to faster speed. Insert the crystal halfway so that the leads are sticking out a bit still. Make a connection between the leads. The gameboy will then freeze. Break the connection. The gameboy will be playing fast again. However, once in awhile glitching occurs in the game when switching back to fast, but I have only noticed problems in Oracle of Ages.
So basically if you want to change speeds easily with the socket method, you will want a small tact switch on the crystal.

You could also do this with a dpst switch and a tact switch.
Doesn't work. It goes back to normal speed, but then it freezes when you use the tact.

But un-freezes when you un-use it? Electroniclly, this does the same thing that the socket thin does.
Hi!
I´ve tryed like themadhacker says and actually its works on gba for gbc games, I think it would be ok on gbc too.
But i discoverded 2 things:
1)If you push the change speed button you can run it lowly, really slowly and no crashes running gbc games
2)when running gba games, if you do the change, the game will crash, but if you retain the button pressed it will not and run slowly (like when gbc cart is used). So, the cristal at 8 mhz combined with the original is too much for gba, and maybe need a slowly cristal, i.e. another of 4 mhz or 6 mhz ( i didn´t tryed out) combined with te swich acting as a selector between 4 (gba) or 8 (gbc) crystals
Otherwise, I only save when the gba is running at normal speed. I dont try to save when is running faster and lose my saves, so I don´t know.
Here are pics, the firs one is for the circuit
The second one is the gba with the mod
Thanks to Basement_Modder !!!

Bad news
I´ve tryed with 4 mhz crystal and it only speed down, but tried with an array of 8 and 4 and crashes again when switch
Good news
When you use only a 4 mhz crystal an change the speed the game not crashes anymore! course it will run slowly, but is safe for now.
In conclusion, i need to borrow some crystals around 5-7 mhz ( i hope fund them in my local store) and try it again.
For future ideas, i will put a triple switch so you can choose between 8 mhz(gb-gbc games) and 5-7 mhz(gba games)

Hi, I´m back with good news
Today i was finished the multiple speed selector on my GBA and works great!
But, there are some GBA games, dont work with the overclock mod (8 or 6 mhz, and i was using a ez flash iv)
Otherwise, all my GB-GBC games worked perfect
Basically, I desolder and re used the old crystal and putted a switch with 2 choses ; 4 mhz or overclock, and derivated that overclock wire to an other switch with a 8 and 6 mhz crystals (the last one is the only who worked fine with the GBA games, the other frezes my GBA)
And other thing: with the removal of the old crystal from the board, when you change the switch its change the speed! no more needed shortcut the wires to make it go and can be done in running system and no freze!
Well, i hope that will be useful for someone.
I cant upload any pics today, but maybe tommorrow. I promise

For his speed selector? No you can't. You need a 3 selection switch.....

I know i'm not going to impress anyone bumping up a thread from 2009 (yeah sorry), but considering this is the only thread of its kind on the internet, this is one of the few chances i have for help (also my thread is not getting any replies).
So if you want to check out my thread, i would appreciate it
viewtopic.php?f=40&t=12923&p=158701#p158701
Im obviously doing something wrong, and im not sure what. The circuit is wired up and nothing happens whether the switch is on/off, during the game, between restarts. The switch has continuity when turned on, but not through the entire circuit (havent tested with power). Im thinking maybe i've soldered to the original crystal incorretly, did i need to remove the ceramic black top? I left it intact and soldered to the two contacts on the inside close to the cPU.
Thanks

Nobody able to lend their opinion?

Maybe its just a bad connection on the side of the crystal?
