Quote from: nesrocks on March 28, 2017, 04:33:59 PMHow would this work? Isn't the game one huge single level?Anyway, the address at 0x864 seem to do just this (a list of songs, a list of CHRs to load, a list of "allow vertical scrolling" flags) etc, but the level itself is not there.0x1CD7 is the list of viper's starting positions and level's starting scrolls.$26 is a ram for current level (0-6)This is (J) rom btw.
Quote from: nesrocks on March 28, 2017, 05:24:31 PMOh, that was the AC version, not the J one, my bad. On the J one the addresses are:partial list of levels (music, chr, vertical scrolling, etc): 0x359viper's starting positions: 0x1BA7level pointers: 0x1802As for $26 you don't need to guess. Open fceux's debugger, set a breakpoint for writes to 26 and play.
Quote from: nesrocks on March 28, 2017, 05:41:43 PMIt is a list of pointers. Pointers are 2 bytes long. In this case (I don't know how long the list is, so lets take the first 4 pointers):109AD199AC998399is109AD199AC998399So you can change their order like soD199109AWhich is D199109ASo just paste that into that address to switch the order.--------------------------------------Pointers are nothing more than addresses. You don't need to know how to convert them, but here goes:109A:1 - switch both bytes (9A10)2 - subtract 10 (9A00) because the NES header is #10 bytes longSo #109A points to $9A00. This is NES memory, but it points to the loaded ROM bank. You can't know which bank is read from just by looking at the ROM, but you can use data logger and the debugger to set breakpoints on read to this address and find out.

Quote from: mrrichard999 on April 11, 2017, 02:40:04 PMIt came from a Japanese site which they used the Japan ROM, not sure if there are any real differences though between the both of them. I was hoping the author of this hack would take advantage of the updates this patch provided though Regardless I am looking forward to this when its done! Gradius hacks are always good!
