Since it's essentially game boy hardware using the SNES clock divided, then why don't the Game Boy Color and Advance speed up or slow down the lesser console games (like GB on the GBC and both GB and GBC on the GBA)? Since their CPUs' primary purpose is to run their own modern games, wouldn't dividing the speed to play the older games cause the same effect?<br /><br />I don't really understand much about tech, just basic "fun" stuff, so this could be a dumb question. I'm sure it's just because the GBC and GBA were designed differently than the Super Game Boy in some way I can't understand when it comes to Game Boy games.Kroneyhttps://www.blogger.com/profile/08477623351426215417noreply@blogger.comtag:blogger.com,1999:blog-6993165553021868648.post-79633775137464043022022-02-14T22:44:17.253-05:002022-02-14T22:44:17.253-05:00I cannot seem to get Super Chase HQ to crash in ei...I cannot seem to get Super Chase HQ to crash in either my GBC or GBA.

Guess the SGB is just scanning the display independently then, and the only reason for the differing clock speed is saving on parts... though I'd be curious to know if there aren't any graphical glitches from time to time when asynchronously scanning the display.

If not, I would expect that speeding the clock up by any amount would not change any behavior or break any compatibility in absolutely any case (unless you speed the clock up to the point where it causes actual hardware glitches). Without any other clock domain to interact with, all the Game Boy and its games know about are clock ticks, regardless of their duration relative to wall clock time.<br /><br />Things break down much more easily for other game consoles, because of all the autonomous internal and external hardware they usually have to interact with. A Game Boy however does not even have to output a video signal with known timing, the DGB CPU directly drives an LCD display that accepts arbitrary timing up to its specs.<br /><br />This lack of constraint on the DMG CPU's clock (if my assumptions are true) also conveniently allows the SGB to have the DMG CPU running at a different frequency derived from the SNES's clock, because it's much easier to have the SGB running synchronously with the SNES than to deal with the asynchronous clock domain crossing that would be necessary when keeping the original Game Boy's frequency.Julien Osterhttps://www.blogger.com/profile/08109834476806811382noreply@blogger.comtag:blogger.com,1999:blog-6993165553021868648.post-15185565783828101442018-03-23T18:31:41.592-04:002018-03-23T18:31:41.592-04:00I added as much information as I could find about ...I added as much information as I could find about the Wide Boys.
