I accidentally posted this in the wrong topic but i have been searching 3 days straight on what opcode controls the VDP write for H32, im currently looking into street fighter 2 and cannot find a vdp write with 8C00, theres only a small handful of VDP writes to 00C00004, so i should be able to narrow it down but nothing is exactly static and uses long addresses like its using DMA for Vram

Usually what im finding on some roms are dynamic writes before it writes to C00004

Im learning how to change H32 and H40 modes, im honestly a little stumped where im at

The example im using is saturday night slam masters, uses H40 and switches to H32, i cannot find the offset where it switches, the vdp debugger on regen will not show offset but the value (0x00) the only other context i have is at offset 555A (33 FC 8C 00 00 C0 00 04) grok is telling me this is the switch to H40 but the breakpoint happens after the licensed by capcom credits, and that is set already to H32

I would love to learn more about this, ive been at this for hours, im not giving up

A challenge for a veteran romhacker, primal rages prototype for genesis uses sprites 2x the size of the final retail version, much closer to the arcade, anyway to add those sprites back in? Also this game stupidly uses 256 mode and ive been looking into the code trying to switch it to 320 or remove the borders

Ive decided to try taking this on, i have some arcade samples and sound effects that i ripped from the arcade game, im very new to this im not even there yet

On the other hand, i wanna start simple, all i want to do is change player lives in the option menu to 99, been trying all day to find where that line of code would be in a hex editor

Im getting somewhere....changed 06 to 63 on address 4BE4 i think, now the counter will move past 5, problem? Once its past 9, it starts showing alphabetical letters and symbols, but the actual in game counter displays correctly

I dont know if this is okay to post this here but i thought for newbies, this info could help


If anyone is interested, last night i figured out how to rip audio/sound effects from MAME arcade roms

1. Find a rom you want
2. Open the zip file, and copy the files to another folder or desktop
3. Run audacity, go to file, import, raw data
4. One of the files inside the mame rom is your audio, this may take some guesswork but you should find it by just importing it and listening to the audio
5. When picking the file, audacity will let you set Hz rate and bit rate, set it to 8Khz 8 bit, some people think this option is for hz sample rate, its not, this will adjust Hz/how fast the audio plays
6. Once you find the right file and the right speed, either save it as a WAV file, or splice up the audio into seperate tracks

Heres the audio i extracted from an arcade game called Calibur .50

The rom file i found was 4.2mb, and just for shit and giggles, i took the infinity and beyond sound bit off of YT, and downsampled it to 8 bit at 22khz

It did bring the file size down quite a bit, but your right, it still would exceed the rom limit, that one sound bit is 80kb

Hmmmmm, is this a limitation of the rom file itself or is it just exceeding a 4mb cart?

Okay interesting, so you could just take the sound effects and voice clips, use better samples, and then just add them to the rom itself

Also two games that i think would highly benefit from CD audio is Vectorman and Comix Zone, sega reeleased an album in the 90s part of a brand called sega tunes, 5 games including vectorman and comix zone got there own special soundtracks

« : 09 Декабрь 2024, 17:40:28 »

Was about to chime in on this, from what i gather from mode 1, it is completely possible to add/enhance sound effects, in the case of toy story, couldn't someone just take the original audio from the movie, edit it in audacity and then replace the sound files?

This is unrelated to audio but sega cd was supposed to be about full motion video, have we found a way to essentially do what MSU on snes can do with adding videos?

I got lots of ideas for genesis games, ideas for improvements/bug fixes

Besides 2 player modes heres a few worth taking a look at

Forgotten Worlds
- When you use a 6 button Controller, the game will not work, it will boot to the intro, and then randomly NOPE game over, tried all the mode tricks, does not work, complete bullshit that this is a problem

Lethal Enforcers
- Did you know that you cannot use a Sega Menacer on lethal enforcers and some other light gun games? How about a fix for that? Light gun game hacks do not exist, we have accessories that very few games actually use which leads me to the next idea

T2 The Arcade Game
- this one will let you use a sega menacer but not a konami justifier, if possible, create a patch that would allow full compatibility between both accessories being used on light gun games that are incompatible, once again this is really stupid that this was never resolved in anyway back then

Steel Talons
- Holy shit what a choppy mess this game is, you wanna talk about optimization of code, road rash had some slowdown, this is painful compared to that, funny thing, i bet you the console could have easily handled this

Final fight has a two player hack, it was removed from RHDN but its still out there in some places, On romhack plaza, super metroid kind of got a two player hack where the 2nd player can control weapons, and im pretty sure i saw on RHDN forums a two player hack for donkey kong country but its not exactly a  stable release

Jungle strike for two is a neat idea

You know how many arcade conversions are missing two player options ....quite a few

Twin cobra, growl, mercs, all of these were either 2 player or 3 player in the arcade

Alright not sure if this is possible and I probably should start a topic about this but i wanted to know if anybody has attempted to make two player hacks for certain sega genesis games? I see two player hacks for NES and Surprisingly SNES, but not genesis

Is it possible to convert songs from calibur 50 that use the Seta X1-010 to Ym2612 and then replace the original genesis versions music, the genesis versions Soundtrack sucks so hard compared to the arcade

Top Gear 2 - Mode 1 (Amiga CD 32 music)

Сборка Top Gear 2 под Retroarch с ядром Genesis Plus GX. Собрал диск с музыкой из Amiga CD 32 версии игры. Сам хак на поддержку Mode 1 за авторством Ti_. Я собрал музыкальный диск и добавил фикс, чтобы корректнее работала пауза. В архиве две версии рома. Одна для игры с разгоном, другая - без.

Tried it on real hardware without the audio files, it worked but both lotus turbo and top gear seem to have some weird issues on emulation and real hardware

Top gear 2: when you crash into barriers, the map screen pops in, this was tested on my model 1, game runs very smooth btw

Lotus turbo challenge: map screen pops in when racing, tested on genesis plus GX, with no overclock and overclock

Twin Cobra - Sega Genesis
Free Play Option that allows you to respawn instantly
Infinite Continues in the option

Let me know what that will cost me


Would love to see the same type of treatment to other shmups on genesis

Thank you for responding so quickly, unfortunately i cannot test this on real hardware due to not having a sega CD or mega SD/Everdrive Pro,

Edmo has expressed interest in seeing if someone will disassemble the code for the sound driver used for this game to see if its possible to replace the audio or use PCM files

Also, i dont know who had that made the overclock mod for lotus turbo challenge, there seems to be a bug on that hack that makes the map screen flash in game while driving

Hey this guy is very interested in a romhack that adds his YM2612  cover to road rash 1

https://m.youtube.com/watch?v=HkkgpumiOdY&lc=Ugydd33aG27PI9bAhPh4AaABAg.AAYz_i6QMGTAAZWlvtym-r

Give it a listen its very good

He did the whole soundtrack



Off topic but related music wise, some guy did a whole brand new conversion of the arcade soundtrack for mortal kombat 1 for master linkueis arcade edition hack, problem is they couldnt figure out how to replace the sound driver, maybe someone could figure that out

Here in America, just made a post about calibur 50 on Sega Genesis

What can be done to this game to bring it much closer and faithful to its arcade version?

Although I’m not in the financial state to discuss prices yet, what would someone charge to take this project on?

And on topic of games that used special controls in the arcade, how would someone translate a better version of the rotary controls for midnight resistance?

Thanks
New to these forums and appreciate all the work that you guys do

« : 16 Октябрь 2024, 00:10:57 »

Hello everyone, new person to these forums and im quite surprised to find out a lot of the great hacks I’ve seen over the years actually started here,

This is not exactly a request but more or less, a discussion about what can be done to fix the bad port of Calibur 50, I have recently played the genesis version and have watched some videos on the arcade version and the difference is miles ahead, the music is badass on the arcade version, and it had twin stick controls

The Genesis port on the other hand is completely watered down, the twin stick layout has now become two buttons that turn your body left or right or the second control scheme is just playing it like any other top down shooter without twin stick controls, the music is just awful, seriously, just terrible, the sound effects are either so quiet that I cannot hear them or they do not exist at all, it’s also missing the intro with the helicopter blowing up, but the weirdest thing is the grenades, I had been playing holding the shoot button wondering why I kept randomly spamming grenades, and then I figured it out, to throw a grenade you double tap B, and yet the game always registers when you let go of B after shooting, he will always end up throwing a grenade….

So I did put together a list of changes or fixes I’d love to see to make this a much much better port

- 6 Button Controller Support for Twin Stick Shooter Controls
- adding sound effects back in that are missing
- Maybe some sort of color hack that would make it look like the arcade game
- Somehow bringing the intro back in but I know that would require a lot of work so that’s probably out of the question
- 2 players added back in


Would love to hear other peoples ideas, in terms of the music, I have considered learning how to use software like deflemask, just trying to find the time these days
