Larry Bank another problem is 150% does not work on any other orention except 0. 90, 260 does not work. it close smartgear out all way.

SmartGear expects game files to be inside of ZIP files. It doesn't really make sense to keep games uncompressed since they would take 2-4X as much disk space.

L.B.

bitbank its very strange that at once point (perhaps the earlier versions like anything below .20) there was no sound clicking, but now it's a problem your not sure of. have you re-writen any sound code since your earlier versions?

Castlevania 3 is mapper #5, not #69
What bugs in Bubble Bobble? Do you mean the vertical scrolling being jumpy?
I haven't debugged Star Tropics 2 yet.

See my website for the list of changes. Thanks for the bug report.

L.B.

didnt work for me...let me make sure i have this right..

open rom.
pause rom.
exit game.
open rom.
sound should work?

i did that and it still clicks.

bitbank i think there still is the clicking sound, but im not sure. it seems like when i play a game and there is a sound playing i can hear the clicking sound. but only while a sound is played, during silence there's nothing. has anyone else noticed this?

Hi James,
Not sure what the trouble is. I'm using wavoutWrite() which is a very basic sound function to pump out sound at 15 blocks per second. I'm sure there are other ways to do it, but this seems to work well on all devices and Desktop Windows.

New build is up with the fix for the NES sound and the TG16 problems:

www.bitbanksoftware.com/smartgear_sp.exe

There are still some problems with the installers that I'm trying to correct. When I "fix" the problems in the WISE script, the CAB file fails to install a shortcut in the \Games folder. I will need to waste more time researching this issue.

L.B.

I got it working on my new Blackjack II. WinMo6 and Mario play nice

yes! the 16bit audio fixed it! you did it bitbank! i can fully play gameboy now.
since we are on the subject of sound, do you know why NES games's sound is too high pitch?

Great, I still have virus issues

It might be related to other software running. Any clues you can provide would be helpful.

Sorry I've been quiet for the last couple of weeks. Trying to ship some commercial products.

I'll try to answer all of the open questions here.

1) SNES support?

I've taken a stab at writing a SNES emulator and it works decently for a few games, but is much too slow. The CPU and sound of the SNES are not that daunting, but it supports many advanced video features with many layers which really kill the performance. It is possible to get full speed SNES on SmartPhones for some of the games which use minimal graphics features. Most games would have to look "wrong" to run at a decent speed. Overall it's not worth the time investment at the moment (especially since it will take away time from projects which actually make money).

2) Slide out keyboard orientation problems?

Windows should remap the direction pad codes when you open or close a sliding keyboard. The only issue might be if it's done AFTER you start playing a game. I have the S710 and old T-Mo MDA to test with. Please send me a set of steps to show how the problem occurs and I'll see if there's anything I can do to resolve it.

3) The clicking sound problem?

The clicking sound has to do with the audio buffers not being filled in sufficient time so there are gaps between the audio blocks. I've been battling this problem for a while and I thought I had it solved, but apparently not. I'll take another look at this one.

4) Use save states from other programs?

Saved games are stored in a programmer-specific, arbitrary way. There are currently no plans to support other software's save states.

5) ARM9 vs. ARM11 optimization?

There are a few new instructions added with the ARMv6 instruction set (in ARM11 CPUs). They won't have a whole lot of effect on game emulation; they're mostly for DSP applications. I code to the ARMv5 instruction set which works on all current and older PDAs. The biggest single factor limiting the speed is access to the display memory. All of the emulators within SmartGear use optimized assembly language CPU and graphics emulation. The remainder of the emulator code is written in C and for the most part does not have time-critical code.

6) Genesis Sound?

I have several powerful devices and will relook at this issue. Perhaps I can add a checkbox to the settings dialog to control it.

7) Strange speed issues?

I don't have access to the devices mentioned with the speed problems. Is it only the HTC TYTN II which shows the problem?

8) Latest release?

I've just wrapped up 0.31. The changes have to do with some fixes to the GameBoy emulation. As pointed out by some users, Pokemon Crystal had problems related to DMA timing and Dragon Warrior III had a bug which was caused by the C compiler. I'll have the build + new info up on my website shortly.

L.B.

I've got the clicking sound aswell... and i'm using v. 30. Maybe it's a stupid question, but wouldn't it be possible to remove the clicking sound with a lowpass filter.. just before the sound is outputted? that shouldn't be hard to code (the lowpass filter i mean) ofcourse I have no idea how the sound system works..

I actually have the same sound problem with PocketNES .. the music is too fast.. and it clicks sometimes.. but it sortof goes away (the clikcs).. PocketGnuboy runs Perfect.. sound and everything.. but it doesn't support using the screen horizontal..
