Any Interest in a Freeplay GBA SP?

[Mlopezmad]

In some ways, I agree that this would be the next logical step.  I, personally, prefer the GBA layout for playing, but the SP is definitely better for pocket portability.  

We have looked into creating a version for the SP shell, but we couldn't figure out how to do it right.  This could be where creating our own custom shell might be a good move.  Unfortunately, that's a very costly route to go down.

Hmm.  Now I'll need to think about this.

I´m amazed at the capacity of the cm3 gba, it is also the best to play for your disposition. But a powerful gba sp would be wonderful for being more compact.
There is a github of a gba sp zero,

it´s fine, but something more powerful would be better.
A 3A + I´m sure it would work for Sp.
Waiting for your next job!
