So After doing lots of Widescreen hacks for The Dreamcast and Sega Saturn I was wondering if anyone is interested in Widescreen hacks for Naomi, Naomi 2, Atomiswave etc.

I've already have some ready to post, but I'd like to know if people is actully interested.

I know tha most purists are gonna yell at me, but hey who cares xD

Since A picture is worth a thousand words, I am talking about this.

good stuff!
mainly because it can be used on real hardware - during game run work RAM can be poked using NetDIMM commands from host PC. so this and other ActionReplay-like things possible.

Omg, yes!! This would be absolutely awesome! Is there any known method of permanently patching the binarys yet?
Thanks for all of your work.

Edit: if you take requests I'd love to Virtua Striker 3 zoomed out plus widescreen.

Wow that was fast,
Thanks a lot Sakuragi that looks beautiful!

Sorry for repeating my question: is there any way to permanently mod the binaries, or make cheat engine run a script during start-up? I was thinking it'd be nice to make something less finicky.

I've only found a zoom modifier for the arcade/naomi version of the game, but I do have a widescreen Hack for the Dreamcast version which is basically the same, so if you want it I can share it.

Oh, And I have no ideaof how to patch the binaries directly, maybe someone with better knowledge can help in that field.

cheers.

Absolutely beautiful, thanks man!
The mayor differences of the two versions are the additional 1500m event and 4-player compatibility on the DC (which makes it superior).
I've been looking into making trainers/scripts that auto patch the addresses when started.
The next step would be something more of a general approach where the script can take an address value pair an patch it to demul (if it a rom has been booted).
This would make a nice addition to any emulation front-end!

Again thanks!

This is amazing! Fantastic work, I'm definitely gonna use this when playing these games!

It's my fav. feature in Dolphin emulator; the ability to play 4:3 games in true widescreen, without any stretching. I don't see as much culling as many gamecube / dreamcast games have: great!

I need to figure out a way to fix the hud in Virtua fighter 4+ the hack behaves differently depending on the version of demul you use.

For Metal SLug, it is a 100% 2D game so it is not possible to make it widescreen, sorry.

Mmmmm..... forget what I said about Metal Slug.

It may have clipping in some areas due to the way the graphics were intended to be displayed

Hi, I am new here and tried to set widescreen hack to vs3 but am not able to do this.
I installed cheatengine
DEmul: Config->Video-> aspect ratio: 16:9
Start game.
In Cheat Engine opened process demul (there were always 2 processes?!)
Clicked "add address manually" and added this 4 addresses from list and set to 4 bytes

But only value from first and third adress was set, the others were 0 and cant be checked.

Can someone please help me? :)
