We all know that Generation I is glitchy, and the game might crash as a result of all that glitchiness. Turns out, there are a lot of patterns in the types of crashes you can encounter. Let's investigate!

More nerd stuff, explaining the STOP instruction: The actual opcode is just 10. However, there's a bug in the GB CPU (might be fixed in GBC?) where it will read the byte following this opcode twice. So if you did something like "stop; inc a", it could increment twice; if you put a multi-byte instruction there, it would be read incorrectly. The official fix for this was to pretend "10 00" is the opcode for STOP, since repeating a NOP is harmless, and "10 xx" where xx ≠ 0 is undefined behavior. This also applies to HALT. That's sometimes called the "double halt bug" since if the instruction immediately after HALT is another HALT, it can get stuck there forever.
@CasualPokePlayer2 жыл бұрын
That's not entirely correct. In the usual case, the second byte is entirely skipped and not executed at all. You can have an invalid instruction in the second byte and the GB would run fine usually. In some cases it is executed, but generally that won't happen (and there is never a "double read" here). The "double read" you refer to only applies to halt, stop does not have this issue. Also, the "double read" only occurs when halt mode is entered while an interrupt is already pending due to rIF and rIE (although ignoring IME here). It's also in reality not a "double read" but rather an extraneous decrement to the PC (so when IME is disabled, it "double reads" the next byte, but when IME is enabled, it instead causes the return address of the interrupt to point to the halt rather than the opcode after halt, the latter case being rare of course given that means rIF would have to change at the exact cycle you enter halt, that or IME is enabled on that cycle (nice for testroms given ei's delay)). Also, of course, due to this, halt after halt doesn't mean it will always be stuck forever (just "can"). You can check more info on STOP on the pandocs here (which includes details on the quirky cases): gbdev.io/pandocs/Reducing_Power_Consumption.html#using-the-stop-instruction

This here is my answer to questions of the kind "Why are you wasting your time digging into old video games?" Because these can serve as excellent "toy"* models for learning skills like assembly level debugging, understanding memory corruption, and reverse engineering. All of these are immensely useful skills of real world computer science. Plus, the "old video games" have a nice, fun incentive for you to learn about these skills, until you start to find the skills themselves to be interesting and motivating enough in their own right. * or rather, real architectures, but simpler than modern counterparts which are much harder to understand when learning from scratch

Need a video on "fixing" crashes, where the game crashes but with a memory editor either remove the erroneous bit of code that caused the crash or repair it then we can see the game can keep running beyond the crash. If I am not mistaken, I believe you did similar before with one or more of the glitch pokemon or was it glitch move/item, but would be nice to see more.
@ryanj42742 жыл бұрын
Well, it would depend on the type of crash. But rarely is just a memory editor going to be enough to recover the CPU, you're going to have to modify the registers and the stack----which would probably require the use of an emulator.

1:37 it seems like @TheZZAZZGlitch is part missingno with the stripey appearance from sprite decompression and causing game corruptions.

Also, the width value used when rendering is correct for the real sprite data it read.
