    The Volgarr the Viking code I posted is a Codebreaker code, meant to be used with Cheat Engine on an emulator. It would be great to hex string the .cdi file to make it permanent.

    I found your codebreaker cheat, but I can't find the Hex String.

    I am going to have to agree with that assessment. OG has really already started to turn into the same kind of place that this used to be, in just under a months time which is highly impressive.

    Yeah it's very similar and all sega console are in the same place.

    Hi, sorry if I might have missed it.
    But is there somebody who collected all hex patches from this thread (including fixes which were posted later for some games) ?
    I'm making myself a nice IDE pack and would like to patch as many games for 16:9 as possible

    If I recall correctly somebody was talking about backing everything up to some google document page or something a few years ago. Not sure if it had been done though.

    I save all patch (codebreaker and hex patch) in a document .txt but it's really a draft... In order to complete the save of @willjay
    I have to organize them better.

    I have only tested PAL FR version, the UK version also contains the hex code, but I have not tested it.
    It may also work

    Shadow Man v1.002 (1999)(Acclaim)(PAL)(M4)

    (track05)

    Code:
    Code:
    find
    09003CC7 08F78DF5 3BD23CC7 08F65CF4 28F83BD4 3BD00B40 9DF936C7
    
    replace
    8DF53CC7 08F77CF9 3BD23CC7 08F65CF4 28F83BD4 3BD00B40 63F936C7
    
    
    render fix...
    find
    0B 40 14 74 FF 88 70 8D 03 6E E8 2E 39 89 D3 60
    replace
    0C 40 14 74 FF 88 70 8D 03 6E E8 2E 39 89 D3 60
    
    This combo looks great the render fix avoid the clipping in third person view but it's unplayable in First person and FMV are "unlookable"...
    It's possible to have a render fix only in third person ?
    It's very close to a perfect widescreen hack.

    Update, you should patch this too.

    FIND
    E8 D5 8B 8C 0C F4 3C F5 2C F8 1C F9 2C FC 3C FD F9 F3 F9 F7 23 D0 08 F6 23 D1 18 FA 62 F0 30 F0

    REPLACE

    C4 59 01 8C 0C F4 3C F5 2C F8 1C F9 2C FC 3C FD F9 F3 F9 F7 23 D0 08 F6 23 D1 18 FA 62 F0 30 F0

    @espirral :
    render fix for shadow man
    find
    0B 40 14 74 FF 88 70 8D 03 6E E8 2E 39 89 D3 60
    replace
    0C 40 14 74 FF 88 70 8D 03 6E E8 2E 39 89 D3 60

    For shadow man with the render fix you did :
    0x0B 40 to 0x0C 40
    then a 0x0B 40 -> jsr @r0 ; sub_8C01742C
    to a 0x0C 40 -> shad r0, R0

    What does the shad fonction do exactly, in the SH4 manual I read : " This instruction performs an arithmetic shift of Rn" what does "arithmetics shift" means exactly ? it adds +1 to Rn ?
    Have you located the R0 for clipping ? I guess @r0 and R0 is not the same thing, what is the difference please ?

    Sorry for my obvious questions.

    Seems like a weird thing but how about a third person + wide hack for vs mode in 18 wheeler. The game clearly can do it in split screen(when u reverse it goes into 3rd person) but it's locked into driver view otherwise.
