To put things in proportion – in 2002 portable console with 16bits of power and color screen was really cutting edge. At that time Doom on a portable gaming console seemed something so technologically advanced that my non-gamer buddy who studied electronics at the time came to just watch me playing it and was in awe.
The gift met with a lot of cheering, as the recollections of both of us wasting long hours on playing the original gray Game Boy were still relatively fresh. And indeed, for the next year or so, before the charm finally wore off, Game Boy Advance has given us both a ton of fun. Castlevania, Doom, Golden Sun, Final Fantasy Tactics, Advance Wars, Fire Emblem – the gameplay of these titles was simply brilliant, sheer fun lasting for hours. It does say something about both games and the console that my best memories of summer 2002 were those spent tucked in the armchair in the corner of the room with Game Boy Advance and a copy of Advance Wars.

Fast forward to 2005, when PSP’s technological prowess seemed almost as if some impossible technological dream materialized on our eyes. Barely three years later after playing Doom on a handheld seemed like a triumph of science (okay, in service of entertainment, but still). It is a shame that this powerhouse did not have a software lineup to follow. But I digress.
Back on topic, you will be happy to hear that Game Boy Advance emulation on PSP is spot on. The only problem is that there is quite a bunch of GBA emulators, most of them abandoned in development, so it’s a bit hard to chose the right one. The best emulator I have found so far is Unofficial GPSP 3.2 Test 8.7 (that is a long name indeed), which I’ve found through comments below this post.
I’ve tried a couple of other emus just for fun, but the gentleman who recommended this version to me in comments was right – it is the best. There’s plenty of options, speed of emulation is excellent, no problems at all. Performance-wise, I have to admit that there are a few titles that slow down a bit at times or lose a couple of frames (this is most noticeable in Golden Sun’s quasi-3D fighting sequences). The vast majority of GBA games, however, runs flawlessly and even those that stutter a little in some sequences are very playable with minor frameskip.
Overall, PSP is giving Game Boy Advance game their well deserved second youth… or maybe third, not sure, Game Boy Advance SP might be considered their second youth… also, there’s Nintendo DS, so it would be fourth youth… and then DS Lite… okay, now this becomes Monty Python sketch, I think I’ll just scratch this line.
Thanks to wonderful PSP screen combined with aliasing effect provided by scaling up GBA games to fit it, these classics look better than ever. Playing Castlevania: Circle of the Moon on PSP made me realize how colourful this game really was the way its creators intended it to be – on original Game Boy Advance’s non-backlit screen it was so dark that player could barely see what was happening. I actually remember reading somewhere that development kits for Game Boy Advance were much brighter, which is why Castlevania turned out too dark on regular GBAs. Sure, it was building dark ambiance, but made this game virtually unplayable if perfect lightning conditions were not available. On PSP screen the colours are vibrant and vivid and game looks better then I remembered it from my first playthrough.
Same goes for other Game Boy Advance titles – they look great, their gameplay is as engrossing as ever plus there are all the perks of using the emulator, such as save states for example. Overall verdict is that emulation of Game Boy Advance on PSP is just great, allowing PSP users to effectively carry in their pockets two consoles in one. Two thumbs up for this incest relationship between Sony and Nintendo
