It may also be bought from a glitch Poké Mart vendor; e.g. through the Yami Shop glitch and Route 11 glitch mart vendor trick~~]]. The inventory can also be filled with this glitch item with the [[j. (0x00) inventory filling map script glitch]]. ==Advanced use== More accurately, this glitch item runs in the middle of two byte map header pointers (these begin at $01AE) at $01D1; misaligned in between Route 6 and Route 7's header pointer (executed as instructions; not followed). When the code is in between Route 10 and Route 11's header pointers, it represents call nc, $BE42. The carry flag is not set; hence $BE42 is executed. SRAM may be locked resulting in the typical "[[game freeze\|rst 38 freeze]]", but can be avoided if the player views the summary of a Pokémon from the party just before using the item, allowing for arbitrary code execution at 00:BE42. Using a pop hl at the end of the code, the stack can be manipulated to safely ret. While theoretically possible, methods to write to 00:BE42 and use [[File:RBItem00.png\|link=]] with the corrupted values have not been published yet. {{clr}} [[Category:Glitch items]] [[Category:Pokémon Red and Blue glitch items]] [[Category:ItemDex]] [[Category:Arbitrary code execution glitch items]]
