Are all flashcarts essentially the same?
No. In general there's four categories.
1 - Old/clone cards. Do not get these, they will not play new games without a lot of hassle (or at all) and are in general a headache. This includes pretty much anything with "R4" in the title other than the original R4. Anything like "R4 Upgrade", "R4-Gold", anything like that is a clone. Do not want. Ever. Period.
2 - Old cards that still get third-party support... like the ORIGINAL R4, with it's Wood R4 firmware. This gets updates, lets you play the latest games, and is simple. However the original R4 only works in a DS/Lite, and doesn't support SDHC. Because of these limitations and it's age, you can get one for like $6 if you don't mind.
3 - More modern cards that still get support. Right now the main one is the Acekard 2i (there were others but they seem to be dying off). This gets updates, plays games, works on a DSi, lets you update stuff wirelessly (including cheats sometimes), works with SDHC, and is generally the card to get if you just want to play DS games and don't like the R4's limits. This is a "mid-range" card (and a very popular one at that) and can be had for about $16.
4 - "Beefy" cards, these have their own onboard processor/RAM so they can do a lot more than normal cards. This include cards like the EX4i, Supercard DSTwo, iPlayer, and maybe others. Generally the Supercard DSTwo is considered the best, as the iPlayer doesn't play commercial ROMs, the EX4i is "rough" and a bit behind, and others seem to be clones. The DSTwo can do much more than other cards, it's got a better SNES emulator, can update itself internally, can play GBA games natively or any DS system (including the DSi, other cards need extra hardware even on the DS/Lite), and a bunch of other stuff thanks to it's onboard processing power... but this is why it's the more expensive cart at about $35.
Jebus I need to make a copy-paste for this sometime...
