There were a couple problems. I don't know why I was grabbing rom_head with the boot resources. Also, sega.o was not being generated correctly. This should be fixed now, if you want to update your svn tree. It's likely that other tweaks might be needed. I'm open to suggestions and input! Also, the r...

I wrote some sound driver stuff in C on the Z80 processor, including 8khz sample playback using SDCC. Lots of cycle counting required, but it is possible to do this in C. (I did go back and change parts into inline assembler, however) The Genesis is going to give you two processors you can program, ...

Ahh, that's what you get when trying to code something late in the evening with a beer in hand. I must have had my boot objects already built as well. 'svn update' and try this one!

Thank you for your patience.

Linker order was wrong. Moved the header to the beginning of the ROM. It's about time I get a flash cart ;)

Created a tool so I can use my midi keyboard with Deflemask. https://code.google.com/p/midi2qwerty/ It is a python script that is a pretty generic midi to keyboard command program, but the default midi-map is for Deflemask commands. This is made for Linux using Xautomation, but it is written in 100%...

A lot of games do use sampled sounds for drums (or record scratches for ToeJam & Earl), on the z80 with the Yamaha chip. Road rash does not use any PCM samples, at least in all the VGM tracks I've dug through.

Another very handy tool is Imagemagick. You can write scripts, or convert and manipulate images in all kinds of interesting ways. All the tools I've mentioned so far are cross platform and will run in Windows too, AFAIK. That being said, if I was forced to use a Windows machine for development (It's...

Huh, I see that. My linker setup was incorrect. Thanks for the feedback!

From working on setting up a decent toolchain myself, it seems that everyone has a different set of tools they prefer. Personally I do my development on Linux and have setup a toolset based of instructions by ChillyWilly ( https://code.google.com/p/gendev/ ) For graphics I keep coming back to the GI...

Enterprise Vs Galaga Demo

Here is a somewhat playable demo of a space ship shooter style game. The Enterprise vs another space ship my girlfriend thinks looks like Galaga. This is showcasing sprites, VGM music, some basic enemy AI, and lots of debugging output. No scrolling backgrounds or collision detection just yet. Enjoy:...

Check out the sound example that is in the sgdk download. It's got examples for playing sounds in a variety of ways on the Genesis, including some multi-channel PCM stuff. I believe it uses magic to make it happen.

The tile order will be different for the sprite than the straight up BMP. I posted a link on another question of yours where I address this question exactly with a shell script to arrange the tiles of a BMP into a spriteable format. I believe there are some other tools to do this (Genres?) Take a lo...

Yes, you can use BMP files as sprite lists.

I did something like you are asking here: viewtopic.php?t=1312

That post was the key to getting this working. I don't use genres, but just load a sprite list BMP, which I put together with some scripts. See:
