As you may already know, Resident Evil 2 was meant to be a completely different game; however, that version was canceled (65-80% done) and was dubbed Resident Evil 1.5.
Recently, team IGAS (yes that's the actual name,not just "The Team") released a slightly modified build of RE 1.5 on February 17th, 2013.
The build, dubbed Magic Zombie Door is unfinished and team IGAS is working on finishing Resident Evil 1.5.
In the meanwhile, MartinBiohazard decided to take a look at the game's coding, and was able to re-enable some rooms as well as other things:
Biohazard 1.5 Mod - Zombies in OFFICE B! - YouTube
Biohazard 1.5 Mod - Beta Basement Playable! - YouTube
Biohazard 1.5 Mod - A lot of zombies in ROOM203! - YouTube
His channel: Canal de MartinBiohazard - YouTube
So, I became curious about 1.5, and peeked around the build and found 2 things:
- There's several more disabled rooms.
- There's no table of contents so it's impossible to look at all the files when you access the iso(with a hex editor,you can look at it's contents) This is something that needs a fix ASAP.
So i tried my best at fixing both things, but for now, I was able to "fix" number 1
FileFactory - Password (password: biohazard152)
The reason I say "fix" is because while it does re-enable the missing rooms in the debug menu; they all cause crashing (Including L tunnel 2, as it has no special fix by me as opposed to Martin's fix of that room) though Debug Room (Martin also fixed that as the Beta Basement) is quite glitchy.
I still haven't been able to fix number 2.
Also here's a link to an interesting post: Resident Evil 1.5 WIP Spoiler Thread (Post your screenshots, findings, observations)
What this post has is a gameshark code that enables you to play as different characters (and costumes for Leon and Elza)
Gemini's post: Open memory, jump to 800B0FF0, change the value there, and reload the room (or walk through a door). 0-1-2 are the values for Leon, 4-5-6 are for Elza, D for alternate Leon (Marvin placeholder?), E for John, and F for "SHERLY!". Everything else simply crashes the game, meaning there's no blue jacket Leon on the disk. Also, most player models can't seem to be able to walk on a staircases.
Oops forgot to mention, there's still some disabled rooms like HIVE ROOM, but some examples of disabled rooms now present in the debug menu: 100 DEBUG ROOM, 201 SAVE ROOM, 202 ZOMBIE TUNNEL, 600 PLATFORM A, 601 PLATFORM B, 602 FUEL CONTROL, 208 ALLGATOR ENT. 20A ALLGATOR EXIT, .
The patch is applied with ips2exe,and lastly i only tested these rooms with epsxe 1.8.0 and with Leon(so they may work with a different emu and Elza,but it's highly unlikely)
