✔ 最佳答案
Oddly no most pokemon games do have there glitches like
-cloning and mew (and other stuff) in red and blue and yellow
-cloning in emerald
-tweaking in Diamond and Pearl
There are other ones the worst glitches (or the best) come out early in production like in Japan before they come to the US. Leaf green has no known besides that one where a legendary dog runs away and never came back (even on the map) ever besides that it is oddly good since it is a basic copy of red and blue so they fixed the glitches.
Edit: Turns out there are but none of them are practical or help full incuding thunder sound lasting surfing music when riding a bike and keen eye paralises. They are kinda stupid but if you wish to see go here
