Play NES games on Vita without VHBL (slow though)

[ReapersRage]

First off, thanks to Demonchild for posting this first on a different forum.

Now that the SDK has been out for a while for the Vita, people have been trying to see what they can do to it. Well, here goes an early treat of what you can do to it.

Right now, this NES emulator can only run around 15 fps which is really slow, but knowing that this will run on the Vita without any VHBL (for those who missed the three times that the exploits came out) seems like it is a great step forward with using legitimate $ony software.

Here is the link to the tutorial on how to get this running on your vita: http://glichxp.com/?p=1986

I wish there were something like this to look forward to on the Mac. VM Ware just sucks up too much resources and I don't have the spare cash for a PC atm...

Try VirtualBox instead of VMWare.

Thanks! I can't import my existing virtual machine but I can try a fresh one to see the difference.

Good, open doors using legitimate software from Sony, but when you start producing emulators without the VHBL, what Sony will do with your software?

Btw this has nothing to do with programming. Moving to correct forum.

Well - author didn't posted any source code...

Main slowdown on Vita is caused by RenderBackground() function in PPU.cs. With is quite weird because there isn't any heavy computation going there...
In release mode on PC it takes about 2 ms to update frame vs ~70 on Vita... I also added timers to know how long it take to update and render frame.

In my Android Xperia Neo it takes:
Frame: ~70
Update: ~54
Render: ~56

Thanks for the news, I hope this can bring ideas into the scene to hopefully soon develop a GBA EMU.
