Got Yoshi's Island GBA for $10, Was it worth it?

Today at a Wal-Mart, I bought Yoshi's Island for GBA for a sale of $10.00. The common MSRP for the title is $29.99. What i'm thinking is, was it worth it? I remember playing the good ol' SNES version quite a while ago with love and joy (before the cartridge's demise), and while I have so far enjoyed the title on a GBA, I feel that I have not experienced the true pixel perfect version of the said title. Should I return the product, and wait for the Virtual Console version? or have I struck gold with the GBA version?

For 10$, you might as well keep it

It's like all the other Advance games - they made it easier, but for the most part, it's the same. Mario Bros. is also included in it

I'll note all the changes here:

Yoshi's Sound effects (you hear his voice in the GBA when he sticks his tongue out, jumps, and hovers instead of hearing the regular sound effects)

Minigame doors in levels would be boarded up once you finished the game so you couldn't play it again, but you can go in as many times as you want in the GBA.

There are extra levels in the game that are even more difficult than the usual extra levels (the usual extra levels are still there though).

In the original, you're 1ups were not saved. In the GBA, they are. So you can easily rack up hundreds of extra lives without doing a marathon run.

Other than that, and the fact that Mario Bros. is included, I can't think of any other changes. The only other thing I noticed was that every once in a great while on the SNES a button would take an extra millisecond to react, causing you to die because a jump needed to be perfectly timed. This very rarely happens, but I noticed it doesn't really happen at all on the GBA (probably just because the GBA is newer).

It's a mario remake.

It's not sma2 or sm64ds.

Win.

I sold it 3 days after buying it. =P

use that money to get an attention span

and i'm a huge yi fan so you're basically asking to die

I am very picky about changes in remakes (as you can see in my Nightmare in Dream Land Vs. Adventure topic). And the minor changes in YI for GBA doesn't bother me, so I would say that is a good indication that they stayed very true to the original.

Completely worth the money, just played my copy two days ago in fact.
