The GBA cartridge bus isn't compatible with a GBC at all. When entering GBC mode, a GBA becomes a GBC. It won't talk to GBA cartridges anymore.
Its a shame to have GBC hardware in my GBASP that I never utilize with my flash cart.
Of course, I can always plug in the original cart, but I really love not having to take all my carts with me.
Thank you.
I will probably add a GB/GBC flash cart to my travel pack.
Even if you enter GBC mode by software, it won't help without the physical switch (and associated 5V circuitry) found in the GBA/GBA SP.
Entering true GBC mode will absolutely not help with Goomba at all, as that is a GBA program.
forgive my igorance..
running from a flash cart does not need 5v. seems to me if we can trick the gba to GBC mode, we should be able to directly open a gbc rom.
or does the GBA need 5v as well?
i only refrence goomba as an example. my thought is to replace goomba completely with a gbc-mode launcher.
Entering true GBC mode will absolutely not help with Goomba at all, as that is a GBA program.
]]>Nintendo just stuck in the GBA portions of the DS components and tried to add GBC compatibility back in, but didn't care and gave up. :) (I figured this because of the whole soft GBC/GBA mode switcher thing that never worked out.)
Or, that they wanted to make lower cost chips, and lazily removed only some of the GBC components, enough to fit on the next smaller die or something.
]]>Also, where the Nintendo logo is supposed to be, there is just nothing, not even the usual black block. What's up with that?
EDIT:
Here are my testing results:
GBA = black screen, sound still works
GBASP (front-lit) = black screen, sound still works
GBM = video and sound work, but no Nintendo logo or black block
NDS = crazy line death
NDSL = crazy line death
I doubt the back-lit GBASP would do anything different, but it would be nice to see what happened.
P.S. Now the Administrator name has changed from Xenu, Dwedit? Are you losing the faith? :P
]]>z80 is not very powerfull but you can use it for some tricks,or a background...
Some similar to ds and advance?
I know nintendo sais it is not posible,but also some "tricks" werent posible on gb and people did it.
maybe need a hardware and software trick??
thanks

]]>can the program damage your flashcard since gbc cartridges run in 5volts mode and the gba ones in 3volts mode?
