Pokémon glitches and emulation accuracy

Emulator accuracy is pretty much ignored when it comes to Gen I and II Pokémon glitches, yet it is very important.

Fun Fact: The Lunar Chase Tech Demo actually switches to an invalid bank, which should work on real hardware and good emulators, but on VC and some less accurate emulators, it doesn't work and the demo's infamous issues arise. (Skip title screen, and loop the beginning part of the mission briefing) People actually had issues running it initially because their emulators sucked.

[@hobbified]

The "some reason" for RAM mirroring is just incomplete address decoding, I'm sure. The SRAM gets selected by the AND of the top two address lines (so, addresses C000-FFFF), and then the bottom 13 address lines go to the RAM itself (since it's an 8kB RAM). That accounts for 15 of the 16 lines, but the 13th bit (the one that makes the difference between C000 and E000) doesn't go anywhere at all, so the value of that bit doesn't affect anything at all. There's several ways they could have done it differently, but all of them would have added at least a little bit of complexity for no tangible benefit.

[@Nickwilde7755]

I totally understand this because I am totally big brain

[@gairisiuil]

are you saying it was implemented BECAUSE of the hardware issue? + why cant the 13th bit just be set as part of the address line? both copies of the ram actually exist on the hardware, it's not like there's some ghost ram the game is trying to read as the result of some hardware issue. i'm confused

[@Kylemsguy]

I’m sure this has been pointed out before, but the reason why echo RAM exists is likely because of the way the RAM bus address lines were hooked up. They’re hooked up in such a way where certain address bits are ignored (for simplicity), so what ends up happening is that it reads from the section of RAM before it. It’s not a “feature,” but rather a side-effect of the hardware’s design. This is why commercial games were banned from using echo RAM.

I first noticed this when I was using Stadium 2 to do the required setup for ACE shenanigans - the 3x speed boost is very helpful. But trying to actually execute anything would usually just boot me out to the "There's a problem with the Transfer Pak" screen. (I've also ran into one of gen 2's glitch Pokemon on Route 45 when I was playing it on Stadium 2, but that... I don't even have a guess for that one. It happened one time out of nowhere and then never again.)

nothing

[@woobgamer5210]

You two are incorrect. VBA has gotten more accurate with new versions And the super glitch move 'qq', has the graphics for scratch and drains half of the damage dealt to a Pokemon in fact all super glitch moves have a hidden effect behind its penchant for causing TMTRAINER and other super glitch effects like lowering stats that don't exist, raising or lowering actual stats for the battle, being a regular attack, causing normal status effects, or *literal nothing* . Some super glitch moves actually have 0 power, 0 accuracy and 0 base pp so there's some you literally cannot use, even if they have an effect or not
