I guess greyscale mode would be too slow.
We could scroll the screen, with hacks for certain games (eg. manic miner) to keep the main sprite on screen.
Maybe, I'll just code a jet set willy type game instead.

button config is just mapping player buttons to some zx spectrum keys
grayscale lib support (undef USE_GRAY in zxconfig.h to disable)
reworked virtual keyboard
now it runs on iPod Mini 2g without using grayscale lib at 16fps withiut cpu boosting and at about 41 fps with boosting
using grayscale lib makes it much slower on iPod mini. don't know how it is on other targets
these are some screenshots of one 48k intro:

http://img100.imageshack.us/img100/6655/castor4g2bppuo6.png <- 2bpp
http://img95.imageshack.us/img95/2443/castornanoie3.png <- the same in color on nano
well, only output needs to be implemented imo...
i'm just not skilled enough to do this... :(
so anyone is welcome to implement this so we can have simple 48k Spectrum emulator :)
* capital E in virtual keyboard maps to Enter
* capital S in virtual keyboard maps to Space
btw, Chuckie The Egg looks even more playable than on iPod mini :)

known bugs:
volume setting doesn't have any influence and sound is still horrible :) ( i doubt i'll manage to get this normal :( )

how did you patched?
do you have apps/plugins/zxbox dir?
The problem was that I was patching from outside the rockbox directory so it created the apps/plugins/zxbox directory.
Problem solved!
now using IRAM correctly (i hope)
i'm attaching an apps/plugins/zxbox.c file separately cause cvsdo refused to produce diff for it :(
anyway it didn't change
* now if any of {height,width} of screen is smaller it would be rescaled to fit the whole screen
(this fixes gigabeat)
