[Release] Dreamchip V4.0

[Zion]

Via Zionmax (http://zionmax.com)


Well, after spending so much time over the last 3-4 weeks coding wandria. i decided to spend one hour on Dreamchip last night.

Now as far as i know the chip8 system is supposed to run at 30fps (might be wrong)

The emulator was running at 27fps last night, after the hour i got it running at 42fps. Feels normal speed to me at least now.

I still havnt done that filebrowser, as im too busy working with wandria to bother :p I just did this to prove to a few people (you know who you are :rolleyes: hehe) that it can get to full speed without taking out the sdl :p

Changelog :

Put in Visable Fps Counter
up to 42fps

very nice man.
you are an exelent coder

it wasn't full speed before o_O?

A few notes: in graphics.c: You only ever use the 32-bit draw mode, so you don't need a switch to check for the color depth before drawing the pixel. Once you remove all those others you unroll drawpixel directly into the drawscene function.

in chip8.c: you don't need the done var in comp_keys, you don't need to check if you have a joystick before opening one (on the psp the joystick isn't really removable =P, as well as the fact that the emulator isn't really usable without it since you have everything based on joybutton* ), and you are still double checking the input stuff.

Some nice improvement though.

Chip8 was a virtual machine (read: no physical chip8 exists) that was designed to be emulated on some extremely old giant computers in the 70s. Since it was purely virtual, and extremely simple, it's been something big to emulate and write homebrew for. http://en.wikipedia.org/wiki/Chip8

LOL, yes it once took computers the size of rooms to run some very basic stuff. We may laugh today but without those early computers, we would not have the vast technology that we do today.

Its fun to go back in time and see where things started once in a while. Great work. Looking forward to future releases also.

how do you put this on the psp. It only has a folder called emulator and no % folder so is it for firmware 1.0? I have 3.03OE-C so can i just put it in the game folder or what?
