Sorry about the wait, but 1.2 version is now up. It has some fixes that reduces the noise issue in most problematic places and some big difficulty tweaks for Arcade mode.

Hey, really cool port.

I have one of the Everdrives (whichever one is older), and tested it out, seems to run okay! There's a tiny bit of white noise near the top of the screen on the title screen, and during the victory animation, but it's not bad. Haven't noticed anything else.
Thanks for ...

I can imagine the possibilities but more over I know the work too. Even the assets could not be simply dropped in place and very little of the code can be re-used so you would need teams for each of the platforms.

Sadly, that is a fair amount of work in any case and as the creator mentioned it ...

Thanks for posting. Uploaded a quick updated version 1.1 with important bugfix, some level alterations (for sake of difficulty) and additional tweaks in PAL version.
I like that for dedication and I am glad that you stuck at it and saw it to completion.
The project has been laying dead for quite a ...

Hi. Almost 6 years ago, I have released a prototype of a game called "Mega Q*bert", but I never finished it due to massive amount of problems with the game's structure. Lately I decided to rewrite it from scratch and it's now done.

Mega Q*bert is a fan adaptation of the popular arcade title for ...

As it was mentioned:

For shadow you got these values : 0, 18, 36, 54, 72, 90, 108, 126
Highlight values are : 126, 144, 162, 180, 198, 216, 234, 255

It will be awesome to know how to do stuff the proper way.

I approve this tutorial.

I guess it's not as easy as it seemed to. Don't want to use loaders and I don't have much of technical knowledge. Gotta stick to the Frog Feast source code.
Thanks for your posts, but I don't mind if somebody has something to add.

That's just padding the output to 256 kB.

Well, I don't know a single bit of ASM. That's nice to know.

I would imagine that you could use mostly the same tools that you use for your Genesis projects, except that you'll need to create an ISO image before burning your game to a disc (I have no idea about the image layout, but there's a tool for it at the rastersoft page apparently).
I compared the ...

I'm planning moving my project from Sega Genesis to Sega CD (it's easier to burn a CD than buying a flashcart, as I may be getting a Sega Mega Drive with Mega CD soon).
Is there any solution similiar to Stef's MiniDevkit? I compiled Frog Feast ( http://frogfeast.rastersoft.net/SegaCDSrc.html ), but ...

Thank you, now I have a single loop. Problem solved.

After your post I realised *pl indeed can be set once and then only modified, but because I suck at using binary operators (I never could really understand them), I'll have hard time trying to make a good loop. Thanks for your post.

I've got another problem I'm trying to solve without good results.
I want to create an illusion of 2 layers of background using only 1 plane. Horizontal scrolling per single line is used.
Here's my C code:
volatile u16 *pw;
volatile u32 *pl;
pw = (u16 *) GFX_DATA_PORT;
pl = (u32 *) GFX_CTRL_PORT ...

Releasing the fixed version of demo.
- Password option doesn't glitch after Game Over screen.
- Music is muted before Game Over screen.
- Q*bert doesn't swear when playing the game after Game Over screen.
- No enemies on screen when starting the game after Game Over screen.
- Massive rebuild of ...
