great! I need me some good GB games I never owned...

Finally; this is the only feature that could have convinced me to buy this DS Lite v1.5 thing

Also, I'm curious about how the scaling will work: I currently play old GB/GBC games on my DS using a flash cart + emulator, and one somewhat limiting issue is that the image has to be rather small in order to be pixel-for-pixel identical to the original, since the dpi of the DS is much higher than these old systems, but there still aren't enough pixels for a full 2x mode, so in order to blow up the image at all, you need some more or less fuzzy math that approximates scaling while losing precision.

Come on, Virtual handheld!

Edit - I wish there was third party though. The really great games may be Nintendo, but other companies did make games worth playing (like Sonic Advance). 8 bucks seems reasonably for a GBA game (same as SNES, which is roughly equivalent hardware) too. I think it's charging to much for a ROM, but it's not outside of reason.

Edit 2 - I'll be getting a DSi as soon as Mario Advance 4 is released. I wonder if it will let us emulate GB(C) and GBA link cables with the DSi's WiFi? Or what about the IR on the GBC?

Edit 3 - What is You vs. Boo?

IM definitely gonna spend my first 1000 nintendo points on the GB/A games that come up when i get the DSi.

If they release Mario Advance 4 for it, they'd better also include all the e-Reader levels (American & Japanese), some of the greatest 2d Mario levels to be created in ages (far better than the entire NSMB, I'd say).

Hey, any of you do realise that there's hidden data of Johto in the Pokemon Diamond/Pearl/Platinum games, right? It was discovered by some users on the Serebii Forums who hacked a ROM and extracted data. There's data in the coding that says, "From Johto," when some Pokemon are traded, and there's stuff relating to the towns from G/S/C in it as well. Nintendo and GameFreak may make expansion packs that are downloadable to the DSi for you to access and travel to Johto from your D/P/Pt games. Even found within the data of D/P/Pt, there is a useless key item that's a ticket for the S.S. Anne:

Man, now I feel like I missed something awesome. I was thinking the eReader levels would be cheap addons with no real substance. I never had an eReader (or even a GBA, I played it on a DS) so I never played them.

Hopefully I have high speed internet by the time the DSi comes out so I can get those free points.

No, they are very well designed levels that combine elements from all the 2D Mario games; below is my YouTube video of one of the Japanese levels.  Also, if you wish to play these and have your own SMA4 ROM (which I can't provide for obvious reasons) and a GBA flash cart, I can send you my .SAV file which contains all 32 levels, the combined US & Japanese sets.  Well worth a playthrough.
