If you purchase this, make sure you get the updated version. He just fixed a problem I had with it not properly optimizing tile palettes.

Megadrive/Genesis clone with a keyboard?

Are there any Genesis/Megadrive clone system that have a keyboard?

After seeing this project, http://playpower.org/, I wondered if it would be possible to use a Genesis/Megadrive clone instead of a NES clone.
The Genesis might be nicely suited to educational games.

Coding practices in 1991

Here's an interesting article about coding practices in 1991:
http://cowboyprogramming.com/2008/11/15 ... s-in-1991/

It covers programming in 68000 assembly mainly.

NEVER put anything on the stack if you have a free register. The more you keep stuff in registers, the faster it will be. That's the ENTIRE REASON to do anything in assembly. If you're going to use the stack, you might as well just use C. NEVER arbitrarily save/restore registers. This goes back to ...

Very interesting file... because even if I force windows to show all the files, I can't see it... But when I search for this file, it find it on c:/windows/ ;)
I think it's a system file, so you would have to uncheck "Hide protected operating system files".

After messing with XGCC for a short amount of time, I would *strongly* recommend moving to the Genesis Mini DevKit or NeoDev (http://frogfeast.rastersoft.net/Files/NeoDev.zip). NeoDev is based on version 2.95.2, which might be a closer match to 2.8.1. If you need help converting your build file (mak...

Re: Moved to XP SP3, and XGCC troubles :/

"Le système ne peut pas executer le programme spécifié" = Windows can't execute the fallowing software. Any idea? What's sure is that I can't go back to SP2 (as my asus laptops drivers can't handle SP2) and no way to go back to 98 . There might be an uninstall for SP3 in Add/Remove programs. Look a...

Pro Motion 6?

Has anyone looked at Pro Motion 6? The new version adds tilemapping features, including the ability to optimize a map for H/V tile flipping, and setting the number of color bits. The tile editor is pretty neat. You can create a screen, and draw as if it is a bitmap, it will create the tiles, based o...

What if the objects change 'z' positions on the screen? Then you have to insert and remove them into the list. I've started the routine; it isn't looking too complicated, at this point. I've coded everything, except for the attachment part. I still have to test it. I plan to put up an example of the...

Sprite sorting?

I'm writing a dynamic sprite list routine, and need to sort the list. I'm curious to find out what value everyone would sort on? My thought would be the bottom on the sprite. This assumes that the sprite data is justified to the bottom of the sprite, and sprites always appear on the ground (no sprit...

Sonic 1/2 sources?

Anyone had a look at the Sonic 1/2 sources available from http://www.hacking-cult.org/?x/2?

I got it to build a binary file, and was able to change a few things, including removing the Sega startup logo.

Re: VDP special tricks around sprites

It is true, I ran across it when I was messing with GBMD. I thought that it was a bug or something, but it is a very nice feature. I use it in my current project to disable sprites drawn onto the status bar. That sprite is first in the list, so any other sprite won't display on status bar. Charles ...

the cw & ch flags are for cropping within a picture bounds, it was not intended that you can "overlap" the picture, it's a bug.
