Working great here! On N810.

Well you're right about BaK of course. I shouldn't have mentioned it. I've just exhausted my options for speedups, with the exception of the final rendering backend, which could use a framebuffer and hardware scaling. My two hopes for the future are that someone will manage to build the fmopl FM- …

According to n0p's page it's a 286-only core. The performance i'm getting is just sad. Betrayal at krondor with sound blaster 1 emulation needs to drop down to 500 cycles. Without music it can run ~ 1500 cycles. Prince of persia with sb1 can run 900 cycles. I'm using moe's fmopl version. I dropped …

Title says it all: I'm trying to get solid playability for 286-class games on the Nokia n810 internet tablet. CPU is 400mhz TI OMAP2420. I generally can get around 1600-1800 cycles without sound blaster emulation, but only 700-1000 cycles with soundblaster (1) before music starts breaking-up ( …

You shouldn't be thinking of x86 and portable in the same breath, like xscale, the x86 based portables suck way too much power. Far better to go with the ARM-based TI OMAP2420 linux pdas (ok 'internet tablets') from Nokia. NO THEY'RE NOT PHONES. check out the Nokia N810 http://www.nseries.com/ …

It runs overall at PC-XT speed - 4.77-8mhz with a fairly high frameskip (2-4).

you definitely need a higher frameskip! Try a frameskip of 3-4. cpu cycles with that frameskip should be around 800 on a 770 or 1100-1200 on a N800. use my dosbox.conf as a starting point. it is optimized for 770.

All alignment problems fixed! thanks to c2woody. Changes in cvs.

c2woody suggested changes which yield proper visual results in vgatest. (AWESOME) From the Jan.25 cvs diff vga_memory.cpp vga_memory.cpp.orig 117,118c117 < //vga.latch.d=((Bit32u*)vga.mem.linear)[start]; < vga.latch.d=host_readd((HostPt)(&((Bit32u*)vga.mem.linear)[start])); --- > vga.latch.d=(( …

Thanks to Serge for pointing-out this trick: "If you set 'echo 3 > /proc/cpu/alignment' and it 'fixes' the problem, alignment issues are really involved. You can also check 'dmesg' output after running dosbox and it will show addresses of instructions causing problems. Setting 'echo 4 > /proc/cpu/ …
