I have a similar question: does anyone know the range for N64 VC games? Also, is it normal for there to be a result in Big Endian in the 0x10000000-0x18000000 range? I searched for a value in PJ64 2.2 and looked for a static value nearby, then searched for the same value (it was 32-bit) from 0x10000000-0x30000000 and came up with 1 result (I checked, and the values I wanted to modify were indeed at the correct offset away from the result, so it is correct). However, changing this value does not have any effect, let alone the desired one, in-game. Is there another region that is Little Endian that I should be searching for? I'm using the latest JGecko U on 5.5.2 USA (Haxchi 2.0 installed from Brain Age). The game I'm trying to hack is Eltale Monsters (the japanese version of Quest 64 in the US, and Holy Magic Century in the UK). It can be found in the Requests section of that iso site.
