This is when you attempt WORD or DWORD access at an odd address, because the Genesis’ Motorola 68000 processor requires data and code to be WORD-aligned (anything larger than a BYTE must always start at an even address). This is very good because there are a few fatal errors that can occur on hardware that aren’t reproduced in emulators, one of the biggest being “Address Error”. In this case, I’ve created a Genesis-side client program and PC-side server program that allow me to run Sonic Megamix over USB instead of having to constantly burn CDs for testing, which makes the process much faster and cheaper, and thus, hardware testing isn’t as much of a pain.
The Mega Everdrive has a USB port that can be used by developers, and has primarily been used for transferring built ROM images for running via some officially-released software. This is important because it’s actually part of what’s happening in the video, even though it’s a cartridge and I’m running a game being developed for CD The first thing you may notice in the video is that I’m using a Mega Everdrive, which I had bought a while ago with some of my “Cool Official Sonic Dude Money”.
Don’t worry that you’ve gone deaf or that your speakers have blown I intentionally excluded sound from the video since it wasn’t important in this case, and there was too much ambience and other stuff going on Testing Via USB Transfer The video isn’t super-high quality because I just wanted to do a quickie update, and recording this setup in that manner was actually pretty difficult. Don’t get terribly used to it, though I certainly won’t be spoiling new things on a daily basis or anything, even if the campaign does pick up and allow me to work on this regularly :P I don’t usually post about it, but in the spirit of trying to get used to the concept of keeping patrons relatively updated, I thought I’d give this a shot. Now that I’ve been promoting my Patreon, I’ve gotten asked several times about Megamix.
