In actuality, the US got JP Blue split into two versions, whereas JP R/G were never released across the pond. If you compare the versions, JP R/G had different overworld and Pokemon graphics from the other games, while JP Blue has the same graphics as our R/B. There are other things too, such as the intro (R/B title screen and intro sound effects are the same as JP Blue's, not R/G). The most significant proof is the trade on Cinnabar Island, where the man says "Your RAICHU went and evolved!" This text string is called by a one-byte value in the data for trade Pokemon ("Raichu" is an in-text variable). In JP Blue, the equivalent trade was a Kadabra.

On the subject of making tables, relative searching works well for English games. In Japanese games, I generally go to a name-select screen, choose specific letters, and make a RAM dump, then do it again and compare the differences. There are probably better ways, but I don't have any Japanese-specific tools and am too lazy to look.

One thing, though... is relative searching as feasible in Japanese games as in English? I've only made a table file for one Japanese game (Keitai Denjuu Telefang), and it reused he and ri rather than having one of each in both kana tables (since they look alike). Is that normal?

Thanks Me-Dave. Your a genius, i havent tried it yet but i looked at the hex for pokemon red and it should be near enough the same as green. So now i just gotta change the text for green using the red one.
thanks

And periods are your friend. Quit making the comma pick up the slack.

Yeah. No Pokemon game outside Japan got the map tile graphics, Pokemon front pics, or Unknown Dungeon layout from Red/Green.

In addition... There's another discovery I made. Surfing on the coastline of Cinnabar or Seafoam in an actual Green cartridge (which I own) produces NO wild Pokemon encounters whatsoever. Therefore, this method of items duplication and finding Missingno does not work.
