Oh, so your HDMI-out works? Mine doesn't. I seriously hope that it's just my miniHDMI-to-HDMI cable... It keeps saying "HDMI DISCONNETED". When you plug-in yours, does it change?
Anyway, I received mine, and flashed it with Bitrider's custom ROM (which is probably the best one out there for S7100Bs). Just one advice, if you do that, install setcpu and raise the minimum frequency. The CPU governor present in the kernel sucks big time and downclocks the CPU down to 300MHz every now and then and the tablet lags massively when upclocking up to 1200MHz (bitrider's ROM sets max CPU to 1,2GHz).
By the way, I tested the UAE4Droid emulator (it was you that tested it too, right [member='KidIce']?) and it sucks massively. I mean, most games don't run at all, and the few ones that run have the SLIGHTLY big problem that when you press the fire button, it ALSO clicks with the mouse. That makes me IMPOSSIBLE to play with It Came from The Desert.
I guess I'll have to buy AnUAE4ALL and hope that it's definitely better.
When it comes to DOS emulation, I've tested AnDOSBox and DosBox Turbo. I still can't decide which is better between these two, but iirc, DosBox Turbo seems to have a slight edge in something.
I still can't decide on the NES and SNES emus. Nesoid/Snesoid are awesome, but SNES9x EX and NES.EMU are too...
I also haven't found yet a solution to the AC3 decoding problem... I hope that bitrider will come up with something.
Plug in the cable to both your monitor and the S7100 and then start HDMI Switch (should have come pre-installed), it should report that the HDMI cable is connected. It will register as disconnected if not also plugged into the monitor. If it's not doing these things then something is obviously wrong... Hope it's your cable. :-/
UAE4Droid: I haven't tried any Cinemaware, and have avoided anything mouse controlled as while the mouse emulation via touch screen works, it's not good enough to play Lemmings or Cannon Fodder w/o some serious frustration. I didn't notice the mouse/joystick buttom problem until you pointed it out, but yeah it's there. My opinion is a bit higher than yours based on a few things... Plays Shadow of the Beast 3 (really, the others are pretty but they suck), Deliverance, Super Frog, Robocod, Speedball 2, Stardust, Rodland, etc. UAE4Droid was a quick and dirty port and had been declared dead at initial release, I wasn't expecting much and it surprised me in a pleasant way. UAE for the PSP blows (none of the games I mentioned run in a playable state on the PSP) and I don't have another handheld (laptop yes, handheld no) that will emulate anything Amiga.
As far as games not running, keep some things in mind: Your default Kickstart ROM should be 1.3, if something doesn't work on that try a previous Kickstart, not a higher one. Most non-AGA Amiga games run on 1.3 or better, some really old stuff (eg Archon, Seven Cities of Gold) is going to require the earlier floppy based Kickstart's. That NTSC switch matters, some things will freeze or Guru if they are in the wrong mode. Try multiple ADF's, I've got 5 different versions of Speedball 2 on my SD right now, I tried 3 of them before I found one that works (didn't try the other two). UAE4Droid does not like trainers . Copper listing is mostly fine, Blitter objects often cause glitching and stability issues (which is weird, the Copper should be the harder thing to emulate).
As for most other system emulators, I keep using what ever works best... This will run this fine but not that, so I use that other one instead for that. I probably never will settle on a "Best" emulator for any 16 bit console.
Sorry about the AC3 thing. :-/
