Personally, I think all these imperfections do the charm of the song. Really, Tiny, you have a cute voice. The first time I heard the song, I found it funny, but then, I started loving it. Now, I can't stop listening to it.
I am myself a programmer (don't have time for DS development, though), I'm also a big fan of freeware and open source, and I try to buy as many games as my budget permits, so, yes, I would really like to give some donation to AKAIO team. I think it's just logical.
If memory storage is not a problem for you, just create a folder on your SD card for each person, with a copy of the ROM in each folder. Then, the .sav will be created in the same folder of the ROM you chose to start. This way, you won't have to change ROM options each time.
What are you talking about? AKAIO 1.5 is not so old. Plus, a lot of loaders have been released since then. I think the last one came out a few days ago, on december 4th.
So, no, it's not discontinued.
It must be that, because I get the same behavior, only before the battery is low for real and the light always shows red. If the battery is fully charged, I don't get this behavior, the light is always green.
One thing is sure, though, never ask questions in a private message. Always ask them in the forum, so everyone can enjoy the answer.
For your second problem, just keep in mind that emulation can't be perfect, especially SNEmulDS which is far from perfection. For each game, just try to change...
Start / system options / advanced settings / save ext.
For a reason or another, this option was resetted. Just tell AKAIO which save extension you are using.
File system corruption. Shit happens. Format your micro sd card using Panasonic SD formatter.
From now, regularly backup your games and saves, never shutdown your DS while a game is being saved, and try not to use cheap or oem micro sd cards.
If it often happens, with different micro sd cards...
Yeah, but if the game has been made in France, the language will be so poor, it will actually make the game useless!
Just a joke, I don't want to restart the old war between Québec and France. "J'te niaise, dude, c'est toute!"
