Re: UMDK manufacturing, part 2: Software

This is what my VA3 Genesis is doing. https://www.youtube.com/watch?v=cQzWmJzCJcQ On mswan's system (A VA6) it runs a lot better, but there is still a small amount of visible speckling and occasionally faulty tile writ Game wise: Mike, on the first screen if the player dies you are not rewriting Pla...

Re: How to create a game rom

I am going to agree that the current audio situation is a nightmare because while the many engines available now support sound effects, none of them support multiple synthesized SFX playing at a time. Synthesized SFX are imo not good anyway... it's quite rare you want to use FM for SFX. PSG would e...

Re: UMDK manufacturing, part 2: Software

I've been testing on my Everdrive, which has been fine. I haven't burned it to an EPROM cartridge yet but I don't expect it to be particularly different.

Visible graphics problems on SGDK-based game

I followed the new wiki setup instructions, and things are good, mostly. This is a pre-TMSS system, but it does not seem to cause issues. Sonic 1 works fine. However, a WIP build of my game has a lot of problems. Palette writes seem corrupted, as do writes to VRAM (be it through DMA or FIFO writes t...

Re: UMDK manufacturing, part 2: Software

...the build is coming along without the visible errors I had early on before Sorry, what build? If you're using the 20151220 binary distribution as described on the wiki you shouldn't have to build anything yourself. I've been out of the loop, I was going on the page 1 instructions still. That's g...

Re: UMDK manufacturing, part 2: Software

Heyo! I had to reinstall my OS for other reasons, so I thought I'd give setting up UMDK another try on a fresh install (before I install the SGDK / Gendev stuff). It seems happier, and the build is coming along without the visible errors I had early on before. I'll report back how well this works.

Re: UMDK manufacturing, part 2: Software

Argh! My package containing most of my belongings is still trapped in the post. On the bright side, another package containing my MD1 with no TMSS has arrived, so once my cartridge is here I can finally run tests on the no-TMSS unit to see what results are.

As I know, because they didn't know about that UMDKs will not work.
We were all 100% clear on the circumstances. Nobody expected a polished, finished, guaranteed-to-work-immediately product.

Re: Linux and Mac OS X GenDev builds with SGDK

useful script ;) just in case, I notice it won't work if CSH is down because the makefile won't exit... also, for my own info, can you confirm me mpc, gmp,... are here only for 32X ? note it would be great to have something like (if TPCDIR not defined, then TPCDIR = xx/xx/xxx) it would be easier to...

I had no idea about the curses interface. This is great! Thanks for the tip.

Re: UMDK manufacturing, part 2: Software

VM images are explicitly not supported: It's not something I'd want to use since I have an actual machine available, but if I can get it working it's an option I want to provide to others. It makes sense to say that it's not officially supported, though, as it can introduce extra less predictable b...

Re: UMDK manufacturing, part 2: Software

I apologize that I won't be able to proceed further with getting my UMDK board to work until some time around Christmas, as my Sega system, UMDK, and lots of other things are currently being mailed home while I move. I began working on a VM image that is all set up and good to go with Debian for SGD...

Re: Video problems on hw

These stand out immediately: VDP_clearPlan(VDP_PLAN_A, 1); VDP_clearPlan(VDP_PLAN_B, 1); Try waiting for DMA completion after each clearPlan. These are non-blocking DMA operations, where you are filling with zero. I remember having a similar problem in a project of mine. I think the palette setting ...

Re: Video problems on hw

Make sure you are not doing any non-blocking VRAM DMA operations without waiting for a previous DMA completion.
