Quote from: MD_Prometh on August 05, 2022, 06:56:19 AMThe King's Field series, Shadow Tower and FFVII would benefit well from more modern control schemes. Certainly be cool to see these kinds of hacks come to fruition one day

You would not be the first person to note the PS dpad is far from something people choose to use from standard selections, never mind the unbridled glory of microswitches. There are however third party offerings that might do something more.
Quote from: FAST6191 on August 05, 2022, 06:01:08 AMI don't know that I have seen such a thing out in the wild at this point but have not been paying much attention as there are vanishingly few games I would opt for the PS1 version of that were made before analogues became a thing.On the face of it then it should just be a controller level hack, with the only problem potentially being if you have to ID/initialise the controller first but if you can do a general control hack that should not be so hard to do. Controller level hacks will see you have to play with code though, and in this case probably not the easiest form of that hack. There are traditionally three approaches in such things1) You alter the debounced state. Every frame the controller's state will be copied to RAM so as to avoid issues with switches being mechanical devices (ever had a mouse double click when you only wanted to do one? This is switch bounce taken to a failure state, it does however happen in all switches as you force through spring, resistance and more besides which makes games tricky if one thing reads pressed and another thing does not, or it reads not pressed despite it being pressed and double jumps/stops running/stops firing....) and everything should operate off that, have something sneak in after the read and change the states of buttons and you have your hack.2) You alter what the game reads. Various things will reach out to the debounced area (or maybe hardware area if it is bad) and check to see if their particular requirements are met. Change this check to something else (or nothing to disable a mechanic). Where 1) is possibly game level (or at least might have one for menus, one for game, one for something else) this is mechanic level so full remaps if there are 500 things that use the X button say get a bit more tedious.3) If the game has some kind of controller settings (even select from three of these premade lists) you play with those. These will essentially be 2 but programmed into the game, hopefully it is a nice simple file in the game or even a setting you can force with a cheat (including force to be something it does not normally allow) but more likely it will be in the code somewhere.You can try watching for what reads the hardware area dealing with controllers, or you can find something that changes as a result of button presses (cast a spell and mana goes down, fire a bullet and the bullet will appear on screen/reduce ammo, jump and your sprite/3d model will jump... and work backwards from those to find its activator. Mana, ammo and such is basic cheat searching, models tend to also be dictated by something in the hardware/memory you can find and read (open the memory viewer to relevant area, do real time updates, get somewhere quiet and then jump, should be obvious what changes, set break on write to that in the debugger and it will start you on the path to the button read).
