View Full Version : A genesis homebrew I made. A point and click SEGA Genesis console.

This is my first genesis homebrew that I thought was worth sharing.
You can download the ROM image with included source code here :arrow: https://docs.google.com/uc?export=download&id=0B-uZnRwZEI1YRzF2eGZOQ0FQMWc&authuser=0
It's a simple point and click style game. Where you click different parts on a genesis circuit board and learn about what each part is.
Just about everything is clickable. The console is based off of a VA6 genesis.

Drag the cursor around with the D-pad, use A or B to click and C to go back to the first screen.
Press START to play a sound demo. Press START+C to stop it

The original VGM file I used was made by someone that goes by the name "Raijin". They are a sega-16 user, but I don't know if he/she is active.

This is the first thing I made that could even be considered a game, I just started programming for the first time a year ago. It's pretty rough
compared to other genesis homebrew, but I'm mostly happy with it. As stated before, the source code is included in the download link.
The .ASM files should be opened in notepad++, otherwise the formatting and spacing might be screwed up. Run the make.bat to build the program.

Here are some screenshots of what it looks like:




And here is a video of it in action



1. Music stutters when changing screens.
2. Bad text formatting. Some text is so close the the edge of the screen that it can get cut off on CRT displays.
3. Console is not drawn perfectly to scale.

Very nice! Reminds me of an old Mac hardware test program that was popular in the mid 90s.

That is a really clever homebrew, I love it. :)

Just a quick update!

I wrote a simple VGM driver that I tested to correctly play the sunset park music from sonic triple trouble on the PSG side, and some music from columns 3 on the FM side.
My VGM driver has very inconstant playback speeds across different emulators though.

Once I get the playback issues worked out, I'll use VGMs for the sound demos. I will also make a simple title screen explaining the controls and such.
I'll call it finished once I have the title screen and music playback.

Here are some samples of how the VGM playback sounds in the fusion emulator.

I decided to use a single sound demo for the whole thing, rather than one FM focused song and one PSG focused song.
The song I used is "bad apple" I found the VGM file on my hard drive. I can't remember where I got it, but the file footer
says it was made by Raijin, who is a sega-16 user.
I wrote the VGM driver, but the actual VGM file is not my work.

Also included is a title screen explaining the controls.

I updated the original post with the new video and download link.
I probably won't update this homebrew again, I'm pretty happy with it now.
