8 Dragons question

Thanks for the response ExiaTreason, but the reason the Prometheus does not appear on the Veldt is because it uses Monster ID #261. Any Monster with an ID above 255 will not appear on the Veldt, nor will any formation above 511 (the "do not appear on Veldt" box should work if these other qualifications are met). This is why it seems much easier to swap the graphics and stats of the Prometheus and White Dragon (and the names), and simply point the formations to the new ID numbers. This should make the Prometheus appear on the Veldt while stopping the White Dragon from appearing, but I am still unsure if the dead dragon will count toward the 8 dragons.

Does anyone know a way I can skip ahead to parts of the game using an emulator to test this stuff? Currently, the only way I know of to do this is to play through the whole game using fast forward... Way too tedious, which is why I ask a lot of questions here.
