Many people have told me that their Toshiba e740 runs pocket nester at 60 fps, full emulation. Now, the Axim has the same processor and same built in memory, 400mhz (xsacale), and 64mb repectivly. Now my ax only runs pocket nester at about between 30 and 45fps. What is the difference that is allowing toshiba to run pocket nester faster. Does anybody own this toshiba and does it run other applications faster?
I could be wrong, but I think that the e740 and the new e750 both have built in video chips. I think they are made by ATI to take some of the load off the processor. I think that explains why it handles video better than the Axim.
The video chip doesn't matter that much because most programs utilize direct access to the screen using GAPI so they skip the chip entirely, only GDI operations would have an effect, I am not sure but I thought nester used GAPI... I could be wrong.... how much free program memory are you alotting? Are both nester and ROMS running from local memory or are they running from a storage card?

maybe running the emu off of CF slows it down? I have no numbers or anything but i would assume running programs straight off of system memory would be faster than peripheral memory. Maybe try running the emu off memory and roms on CF card then both off of memory and tell us if you get any different numbers.

Just in load time. The PPC will transfer the program files to system memory when you open it up. However, the ROMs will still be accessed on the CF card during play.
the e740 and the axim have pretty much the same configuration (processor, memory, etc) BUT the e740 was optimized (both software and hardware) for the increased bus size of the pxa255 processor, while the axim only supports a bus speed of 100mhz (only half of the e740) And this cannot be changed because the axims bus problems lie in the hardware

Nope you are confused with the e750, the e740 was the first XScale device and it's bus is only 100mhz. the e750 is optimized for the PXA255 and was released just recently.

yea your right... the e750 was the one optimized...
