DC widescreen games

[rooster]

This is a useful thread! The first game I tried once I got a widescreen TV was F355 Challenge. Go figure, eh? I'll try out other games not mentioned here and report if I find any more that display in proper 16:9.
Also, some games look okay if they've been 'stretched' to fit a widescreen. For example, Bomberman - you wouldn't notice it's been stretched since the characters' proportions are already cartoonish.

I can confirm that V-Rally does support 16:9, and it works through VGA.

I never saw on back of dvds anamorphic or whatever, just letterbox.

STURMWIND also supports widescreen.

Hey everyone. I'm a longtime DC fan, and just recently started using Demul since I got a new PC.

I'm dying to try these widescreen codes, but I can't seem to get any to work. Can someone PLEASE, PLEASE help me figure it out?

Here is what I am doing:

1) Run a game in Demul (works great, using latest version).
2) Run Cheat Engine 6.6 and select the Demul exe.
3) Select "Enter address manually"
4) For example if U play Soul Calibur USA, I use this code: 022D6138 3F400000. So I enter 022D6138 as the address, then enter 3F400000 as the hexadecimal value. Then check the box.

Now, so far not a single code has worked, and I have searched everywhere for an explanation.

I did find a premade Chear Engine file containing widescreen codes for Shenmue, and when I use that they DO WORK! So, I'm wondering if the codes I'm seeing posted only work on a real Dremcast?

Do I need to convert the codes somehow to work on Cheat Engine with Demul? If so, how?

Thank you to anyone who can help me out. I've spent hours trying to get things to work and have nearly given up now. :-/

Those are CodeBreaker codes intended for the CodeBreaker cheat disc. You don't use them with Cheat Engine. If Demul has support for CB codes, you would enter 022D6138 3F400000 as a cheat code.

Yeah, I figured that was the case.

Demul doesn't have cheat abilities, so we have to use Cheat Engine to enter codes.

How can I convert the Codebreaker cheat address to use with Cheat Engine on PC?

You don't use Cheat Engine with emulators. You want to apply the cheat to the emulated game, not the emulator.

That is what I'm doing. Please read my first post where I explained everything.

The problem is that almost all the cheats posted oline are for use on CodeBreaker + DC, and we need different addresses for Cheat Engine + Demul. The question is, is there a formula to convert a CB address to use on CE with Demul?

For example, here is the 16:9 widescreen code for Shenmue USA (the only game I could find with a working Cheat Engine code):

CodeBreaker: 02230250 – 43800000
Cheat Engine (Demul): 2C230250 - 43800000

That code works, and I am able to make Shenmue 16:9 on Demul via Cheat Engine.

Now, looking at it, and I am not a programmer, it's obvious that the first 2 characters are different. 02 vs 2C. So I tried another CodeBreaker code that started with 02 and changed that to 2C, but that didn't work. Beyond that, I have no idea how to convert the addresses. But there must be a way. I'm not technically knowledgeable enough to figure it out, but I'm hoping someone here may be, or can pass the question onto someone they know in the DC scene who is.

UPDATE: ha, my method does work!!! I just converted the Crazy Taxi USA code by changing the 02 to 2C and it changed the aspect ratio for use in 16:9. I think the other codes I tried before may have been incorrect. Now, how do I convert an address that doesn't start with 02?

Crazy Taxi (USA) working 16:9 code:
CodeBreaker: 022B08B0 - 43700000 (438E38E4 may look better)
Cheat Engine + Demul: 2C2B08B0 - 43700000 (438E38E4 may look better)

***I will add more codes below that I confirm working using Cheat Engine 6.6 with Demul 0.7a as I find them. Seems like almost all codes start with 02, so maybe the 2C conversion will be very useful.

Daytona USA (USA) working 16:9 code:
CodeBreaker: 021FC6D0 – 43700000 (438E38E4 may look better)
Cheat Engine + Demul: 2C1FC6D0 – 43700000 (438E38E4 may look better)

Soul Calibur (USA) working 16:9 code + No Clipping code:
CodeBreaker: 02266C28 - 3F400000, 022D6138 – 3E800000
Cheat Engine + Demul: 2C266C28 - 3F400000, 2C2D6138 – 3E800000

The 02 means that the CB code is performing a 32-bit write to the specified address.
