Thanks for the link (RapidShare), Murdock!
DOSBox is awesome now I can play classic DOS games on PSP like Mario, Super Angelo, Wolfenstein 3D, Spear of Destiny and lot more.

When I tried loading Alien Attack, Space Invaders clone, I got a BSOD. Wolfenstein 3D works OK though, but runs a little bit slower than on DOSBox Build 1.07.2007.

I set 3000 CPU cycles and 32 MB of memory in dosbox.conf.
Is it right? My PSP is 333 MHz and 32 MB of RAM.

Look at murdock's post on the first page of this thread and make an effort to type in English in a public forum.

I'd really like to hear a 'gods voice' about the irq.

atm, my best guess is that it emulates an x86 interrupt priority level,
Setting too high can swamp the CPU and slow down graphics, too
low can cause sound dropout.

I know this post comes late, but I just wanted to clarify the purpose of interrupts, so people don't go changing their interrupt values due to what Dangee is saying.

There is no "priority level" when it comes to an interrupt, an interrupt is exactly what it says it is. In a nutshell, when a piece of hardware wants CPU time, it puts a request on the interrupt line (I believe the SB16 emulation uses line 5 by default). The CPU will then jump and handle that interrupt request.

Adjusted the interrupt value in the dosbox.conf will have not effect on performance.
