I just tried it too....
I agree, it needs a read me in the archive with the setup instructions.
I found the website and by poking around I found simple setup instructions in the download section, although I expected it to be somewhere else.
But definitely a readme file in the archive should be a must.
I also had trouble patching the .nds file, I tried the usual dlditool but for some reason it still wouldn't run on my old supercard SD ( which for convenience is what I use for emulation ).
So just to see if it was a patching problem or was I missing files ( this kind of error message should be given at the start to clarify things !) I put it on my slot 1 G6 Real ( which has auto dldi patching ) and it worked.
Now the emulation itself is great, I tried some MSX disks and roms ( HERO, Bruce Lee ) and some MSX2 disks and roms ( Aleste 2, Nemesis 2 ) and they worked flawlessly , albeit a little slow , but I prefer it that way compared to having frame skips ( I hate when a scrolling is already choppy and it's made even worse ) .
Sound was spot on, but very low ! I could barely hear it from the DSL speakers, I am sure there is a way in the devkit to adjust the volume levels.
Speaking of sound, I couldn't hear any FM music in aleste 2, just the AY sound, while the cartidge based nemesis 2 had the proper multichannel music.
The keyboard is simple, which is not a problem, but sometime while pressing keys they would get corrupt, like displaying japanese characters instead.
And the file selection is nice, but could use some scrolling tabs instead of using the d-pad and a double tap should be able to select a file.
The scaling is great, it worked really nicely, but it would be nice to see the changes in real time.
Also a reset button would be helpful, instead of switching it on and off.
Yeah all it all a solid emulator, I will try more games on it, but surely speed needs to be improved.
I don't know how that would be feasible on the DS , but games should run faster.
Maybe when somebody hacks the DSi there would be a way to use the little extra cpu power and improve the emulation speed, but that remains to be seen.
Anyway I had a blast playing the MSX H.E.R.O on my DS, it's my favorite version !
Good job!
