ROM Hacking Discussion / [PSX] Need For Speed 2 thread
« on: April 13, 2015, 10:00:30 pm »
Another NFS for PlayStation I've got my dirty hands into.

So, as I've discovered once, cars' .GEO files are 100% identical to those from the PC version, making it a potentially first NFS game for PSX to feature addon cars that aren't just texture swaps.
The .QPS files' mystery has also been solved - a slightly edited FSHtool, which I named "PSHtool", flawlessly converts them to .PSH files, allowing their modification.
But here comes the braking point: the only thing that keeps me from throwing in a first new car (Ford Mustang Mach III, to be specific) I've even prepared textures for is a lack of program that could build a .PSH file from ground up: Leo's PSH editor only allows replacing TIMs with the exactly same size, and PSicture is just a texture viewer with no import function. Other .TIM editors I know don't support PSH files. The only solution I see - replacing .BMP support of FSHtool with .TIM support - requires knowledge of programming languages, which I lack.

Other files identical to their PC counterparts:
- Cars:
- Tracks:
(Z)TR0*.QPS (not PSX texture files, these are ZTR00*.QPS)

Some files lack any counterparts (like Z%CAR%.QQS), probably thanks to different platform architecture; some are only slightly different (like, .MAP files only have different ends).

Recently I've been struck with the idea of hacking Test Drive 2 for Mega Drive/Genesis with the purpose to add more variety to the game (3 cars, 3 scenarios and 3 short music tracks get boring fast IMO). However, I never dealt with ROM-based games, so I have no idea what to do. For now I'd like to see the game's structure, to see if I can actually add anything (like in those fancy Dune 2 hacks with six houses to choose from) or I'm limited to texture editing.

Thanks in advance.

ROM Hacking Discussion / [PSX] NFS High Stakes - full edition (HELP NEEDED)

My kinda hack of NFS for for PlayStation. At the moment it's not active due to personal reasons. YAY, REVIVED!
As a base, the US [NTSC] version is chosen. (at the moment Australian [PAL] version is used, later everything will be ported to US [NTSC] version]

The tasks of my work:
- To add 3 region-only cars (Australian-only HSV GTS, Ford Falcon XR8 and Japanese-only Nissan Skyline R34 GT-R V-spec) in the game - DONE/TODO (HSV and Ford are fine; regarding Nissan - problems are being encountered, see details below)
- To allow the player to drive Ferraris and Mercedeses in Hot Pursuit mode without of using third-party cheats like gameshark - DONE
- To enable leftover blue-and-red vidwalls for police cars - DONE/TODO (Caprice's vidwall is plain blue, so it has to be edited)
- To add cars' own interior's textures instead of placeholder interior texture present on all the ingame cars - TODO (only Diablo SV's interior textures are added, along with its actual rims instead of Z3's it originally had)
- If possible, to add SV markings on Diablo SV - TODO (cancelled, as an addition of second side texture and edition of the car's model will be needed)
- If possible, change the French police cars' lightbars to blue or blue-and-yellow - TODO (replacing the French cops with German cops, hoping that they have different dummies for lightbars' lights, didn't help, I'll look for the other way... upd: probably the source of the problem is the same one that doesn't let me properly add Skyline without replacing HSV - see below)

Currently, this HS's revision only exists as the patch for the Japanese version of the game, Over Drivin' 4, as back then I didn't know how to re-build games' images, and Japanese version had Australian cars as leftovers; besides, it only had one or two tasks done. It, along with the screenshots of what's done, are hosted on another site.
