-Screw GameFaqs. Help is lame. Occasional "geez I've scoured this place for hours and nothing..." is fine. Even more awesome when you know someone who's played.
I'm really glad Nintendo made the choice to make the DS backwards-compatible with GBA games.

I have several games in my GBA/DS library that are ports of the original NES games...
Do you have Metroid? I've never looked into whether or not it's like the FDS or NES one. That is: Does it have save files?
It does make me wonder why it's only NES gamse that were ported, but I suppose the SNES stuff was better left for the Wii Virtual Console.
SNES is a pain to put on GBA. From what I gather, processing power / sound/ layers. I don't think they can convert the sound properly (see Mother 1+2) so they have to re-do the sound.
The SNES has so many graphical LAYERS to deal with. Like, a screen is made up of several transparent sheets, each with it's own graphics contribution, like: background, text, text box, character sprite.
SO... I think they had to re-do everything, to put an SNES game on the GBA.
I'm still wondering how the hell they got Yoshi's Story (N64) to run on the GBA demo forever ago.
I keep drifting back and forth with the idea of finding as many NES-to-GBA ports as I can and essentially recreating my old NES library for the DS. Some titles never made it over, but I kind of like the idea.
With a slot-1 device for your DS, you can play (almost) any NES game you want. All on one cart - no messing with troublesome GBA cart switching. Also, ANY game - you're not limited to the GBA's library. Foreign titles not released in the US are not to be forgotten!
There is limited SNES support, but it's still possible.
You can play Genesis and Master System stuff, Game Boy stuff, Neo Geo, Game Gear. And probably other stuff I don't remember/use.
I told you about these slot-1 flashcarts, when I recommended some DS midi controllers.
I do think a slot-1 flashcart would serve you well.
