Printing to the Screen Using a PRX ?

[MiG]

I've got the following code for a PRX, just as a test really, but anyway, here it is, i'm new to creating PRX's so i'm wondering if the techniques are any diff.

O yea, why doesnt it do my desired result ?

}

debug printf isn't available in the psp kernel.
follow devhook guidelines for makefile

Theres no Pre-Worked Out Way of printing to the Screen... I did many Trial and Error Attempts on doing a proper Text-Blitting (Output) to Screen...

The Way it works without relying on the DebugScreen Stuff is calling to the VRAM Framebuffer and directly write Color Values in the currently used BPP Rate to the Screen...

I enhanced the Code Booster used for his VSH Extender a bit myself using Information I gathered over Time...

You can find a extensive and proper working Blit-Library of mine inside the Musou-Cheating Device R5 Sources you can find on my Devspace http://coldbird.lan.st

This should help you out...

thanks all, i thought it wouldnt have been as simple as that.. lol.

quick edit - i cant find the "Mosou-Cheating Device" you reffered to in your post. *scratches head*

Subsection Cheating Devices / Shin Sangokumusou 2nd Evolution / Musou[J]R5.rar

That was it I think... haha

So it is :P anyways, i found what i needed in the Devhook SDK, but when i try and listen for keypresses Games dont respond to key presses and all..

for instance, the keys are unresponsive and the in game camera is allover the place

[weltall]

you must use peek else you will remove the controller data

[Coldbird]

yup... keep peekbuffer positive...

I still suggest you take a close look at my Musou Device... It should have everything ready for use - even stuff the DHSDK cant offer you...

Like Multi-BPP Blitting and of course Resetting of Screen (that one thought aint too exclusive - as its easy to code...)
