Wich is the best? A hack PSP or a DS with an R4 In terms of homebrews.
FOr example:
-for chatting
I honestly think that the PSP is better for chatting. The only reason is because I'm used to using a keyboard to chat, and not using the stylus. Besides, I prefer the bigger screen provided by the PSP so I can see the text better, but that's just me. Also, the PSP has Skype, which is pretty cool to have on a console. But if Skype is not your thing and you like using the stylus to chat, then the DS wins this one.
-for navigating with a browser
The PSP, hands down. The original DS browser is crap, especially when compared to the PSP. Plus, no flashcard browsers can even compare to the PSP. The PSP user interface is beautiful, easy to use, has TONS of customization options, and has access to lots of cool features. Sometimes I turn on my PSP just to mess around in the XMB. :3
-for listen to music
The PSP. It natively supports music playing, unlike the DS. The sound of the music is great, rivaling that of the current MP3 players out there in the market. The DS sounds pretty bad if used for music (IMO), and the user interface is nothing like that of the PSP.
-for watching videos (excluding the fact that the psp screen is panoramic and better than the psp)
Let me just ask you this. Have you SEEN what videos look like in .dpg? 'Nuff said. The PSP supports other fle types, and looks way better. It's actually enjoyable to watch movies in it.
-for emulating nes, supernes, and n64 games
PSP. It supports full speed NES/SNES/GBC/GBA/ and the other lesser known systems. I only use it to play GBA, and it's incredible. You cna stretch out the image to fit the PSP's screen, and the games look really good. It supports cheats and full speed for all games, as far as I know. I've never had a problem with any game I've thrown at it.
-for homebrew games
I'd say the PSP, but that's purely a personal choice. On the DS, the only good homebrew games I have found that are as fun as real games are Meteora and Warcraft Tower Defense. On the other hand, the PSP has some really fun homebrew, like Counter Strike, PSP Revolution (which, for me, is literally HOURS of fun), Cave Story, CSPSP, Doom, and there are many others I haven't tried yet.
-etc.
Now, game-wise, the DS DESTROYS the PSP. Honestly, the PSP has horrible games. They are all crappy remakes, except for the MAYBE 7 or 8 good games it has. I really don't know what went wrong, because it could have been such an awesome console... but the games are horrible. Other than the staple Crisis Core, Janne D'Arc, GoW:CoO, and maybe Dissidia and Birth by Sleep (which aren't even out yet), I can't think of any other good games off the top of my head. On the other hand, I can think of at LEAST 10 good games for the DS right off the top of my head, without even looking at my flashcart. The games for the DS may not be high-quality and "epic", but they are innovative, fun, and original. I must have at least 70 games in my computer for my DS that I'm still waiting to play.
