Re: MegaLD Dumping Project

If anyone's interested in reading a bit about the evolution of the software video decoding efforts, the best record is captured here: https://forum.lddb.com/viewtopic.php?f=32&t=2671 This doesn't contain some of the more recent discussions and results, but it has a lot of the steps leading up to whe...

Re: MegaLD Dumping Project

I've never done a youtube video before, but that's probably the best way to sum up where things are right now, as I can show visually what's been done, the hardware involved, and what's still pending and why it's important. To try and give a 30 second summary, here's basically where things are: 1. I...

Re: Active Disassembly

That's the key to the active disassembly feature in Exodus Miquel, is that it does actually emulate the game, and uses real-world results from executing the actual code to guide the disassembly process. You actually perform your disassembly by playing the game, while active disassembly runs in the b...

Re: Active Disassembly - Post Processor

Thanks for your suggestions and feedback. I'm glad you're finding the current features useful. There is certainly a lot that could be done to the output from active disassembly to make the generated code more useful. One of the challenges though is keeping things generic and platform independent. I'...

Re: Exodus 2.1 release soon (Now available!)

I might have to check out your disassembly. TJ&E is one of my favorites from the Mega Drive, and the theme music is actually the current ringtone on my phone. :) I'm certainly up to helping with the random crash problem. If you can give me a bit more info about cases where you're seeing the issue oc...

Re: Exodus 2.1 release soon (Now available!)

I thought you could send attachments here via PM, but it looks like I'm mistaken. Best way is probably using a file drop service like https://uploadfiles.io and PM'ing me the link. If the program hangs rather than crashes it won't usually generate a crash report, but you can create one manually whil...

Re: Exodus 2.1 release soon (Now available!)

I wasn't aware of these issues, and it's not something I've encountered. I'll try and reproduce it. For some more info though, when you say it "crashes", what exactly do you see? Does the program terminate with some kind of error, or does it "lock up" and become unresponsive? Do you have any crash r...

Re: Trying to compile Exodus

Sorry! Unfortunately the VS2017 installer is even more of a monster, but it'll only download what you select. If your downloads take awhile, you might want to be conservative and turn off stuff you don't need to save some time. If space is an issue, you'll also need to be selective. If you download ...

Re: Mega Drive - Known Compatibility Issues

Thanks for your feedback. Unfortunately there are more than a few games that have problems like this right now. Most of them that I've traced to date come back to the same thing, which is a lack of sub-opcode timing emulation. Without that, timing events in the system often appear from the CPU persp...

Re: Trying to compile Exodus

Sorry, that's my bad. I upgraded the toolchain with the latest release, but I forgot to update those instructions. Exodus now requires VS2017 to compile. You can get that from the main Visual Studio download page at https://visualstudio.microsoft.com/downloads/ . Note that VS2017 has a fairly comple...

Re: Exodus 2.1 release soon (Now available!)

I was actually surprised to see I haven't added this feature. I've done this form of capture in the past, but I think I hacked it into dev builds for internal debugging before. I've just added continuous trace logging to an output file in a commit to the repository. If you're able to perform a build...

Re: Exodus 2.1 release soon (Now available!)

There's definitely work to do on the YM2612 core. It was already at a pretty advanced state though, so seeing as it's just me working on Exodus right now, I'm going to be focusing on other areas first that are in greater need of attention. I like to independently construct hardware tests to verify n...

Re: Exodus 2.1 release soon (Now available!)

When you do get around to that: the bus arbiter in the Sega CD side actually understand the 68k TAS instruction, so that the subcpu can use it successfully on the Sega CD RAMs. So the 68k CPU core should probably implement the instruction correctly and leave to the bus arbiter to break it as needed...

Re: Exodus 2.1 release soon (Now available!)

It's worth noting that my Mega Drive VDP core currently doesn't implement mode 4 support. It requires a whole set of tests to be carried out, which I haven't done so far. Even if I had mode 4 support in the Mega Drive VDP core though, the Master System VDP is actually quite different. Not only does ...
