Click the ON key of the HP48 or press the START button of your PSP (it maps the ON button of the HP calculator)

Right

Great ! By the way there are some X86 assembler codes inside (to improve performances) that should be rewritten in MIPS R4000, so it's a little bit harder than X48, but of course it's feasible.

How can I make it look like it has 10 notches all sides?

it shows 2*6 notches on the x and 2*3 notches on the y axis but the extents you've specified are the actual ones - try tracing the function - it will trace exactly in the specified domain.

oh, since this is my first post in this thread - kudos to zx-81 for porting this magnificent emulator! it's a must-have piece of psp homebrew.

Thanks zx-81 for your answer of my post.
I reformat the ms of 32MB and put the hp48bin file just like you said, and... done!!!!
Its a amazing homebrew for the psp
psp runs everything...

@1timeuser : lol

@Gwimmel: unfortunately the source code is old and not portable (using __asm__ statements with i86 ASM, that makes gcc 3.x and 4 crash). With many patchs and efforts i succeed to compile it under linux, and it seems to work
