For Reviews and Purists: Where does Emulation Begin?
Posted: June 6th, 2014, 9:24 am
I am not trying to poke a hornets nest about morality / legality of emulation here. Just technically, where does emulation begin? This comes to mind as the Critic reviews Gameboy titles, and there are so many ways to play these games, including as one poster pointed out, pretty well on your 3DS. Also, some of us really want the full 'back in the day' experience.
In general, I thought Dave's policy was 'original hardware', although he felt free to use whatever controller worked best. Yet with the Gameboy reviews, things are getting murky. Maybe given the review scale of A+ to F-, there is not enough granularity to matter, or maybe you think it does.
For you to play an Atari 2600 game on your colecovision expansion, its not emulation. Colecovision cloned the 2600, literally. It should be the same experience as playing on an Atari 2600 or a Coleco Gemini or a Colecovision expansion.
For you to play that Atari 2600 game on your Atari 7800, the 7800 goes into 2600 backwards compatibility mode. While it has much the same chipset, it does have to limit things and use other ways to get there. So, even beginning with the Atari 7800, its likely not perfect emulation for the Atari 2600 (Atarifever and others can chime in here)
For you to play your Sega Master System game on your Genesis with Power Base Converter, it uses a pass through to the Z80 co-processor that was the main co-processor in the SMS. It should be pretty good again, but is it perfect? Is the speed right? How is the sound? Going to the Genesis controller would probably change things to, but Dave seems okay with that.
I think a pass through is also how the GBA/SP works as well for Gameboy emulation. Yet even there the SP has a backlight, and that is going to skew color saturation. Does that matter? How is the speed and sound here too?
If you have a 'famiclone', then you again have some chipset trying to duplicate the famicom, but it may differ from machine to machine. Modern ones may have an "NES on a Chip" design. The modern Flashback 2 emulated the Atari hardware differently than the later Flashback 3's and 4's. The Retron series also presents both utility, but issues like this as well. I don't think we'll see Dave reviewing SNES games based on playing them on Retron 5.
When Dave uses that Super Game Boy for the Gameboy reviews, and that SNES adapter has the Gameboy CPU in there, but supposedly runs a trifle fast. Its also using SNES controllers obviously, but again, Dave doesn't care about that so much. The Game Boy Player in the Gamecube is like the Super Game Boy, I believe, containing the GBA chipset. Maybe not - maybe its just close to the chipset with some differences. Anyone know?
And so on. By the time we get to the 3DS playing Gameboy games (not DS games, but GB games), its down to pure software emulation, right? Maybe its good solid emulation, good legal Nintendo emulation, buts it still just software emulation. If the door is open for emulation, then there are all sorts of devices and emulators that come into play. Dave should likely stay away from any emulation, including on the WiiU or 3DS, if the policy is for original hardware.
If the Critic wants to say 'and this is how good the game is' where is the line? (In particular, where is the line for Gameboy games, but in general, where is the line?)
