Re: SEGA CD Mode 1
I think Genesis Plus GX also supports Mode 1 boot these days, but I've personally had trouble figuring out how to get it running. Hi, You only need to have a .cue file with same basename as the ROM file you load, in same directory, and Sega CD Mode 1 should automatically be enabled. Alternatively, ...

Re: SEGA CD Mode 1
FWIW, BlastEm nightly builds also have Mode 1 support these days and might run on a slightly less beefy machine. My CD compatibility is currently a fair bit worse at the moment, though I do much better on mcd-verficator. I think Genesis Plus GX also supports Mode 1 boot these days, but I've persona...

Re: SEGA CD Mode 1
You might try ARES. It has better mode 1 support (it's the emulator Vic uses for testing mode 1 support in D32XR). The main problem with ares is that it takes a pretty beefy computer. If it acts the same, then the problem is likely in the code rather than the emulator. Vic posted his Genesis+CD pcm...

Re: Sega CD Mode 1 support functions for SGDK
I suppose that after a certain amount of time, or if the user selects something from the menu to disable the cd, you could reset the asic and the sub cpu. That should do it. /* * Reset the Gate Array - this specific sequence of writes is recognized by * the gate array as a reset sequence, clearing ...

Re: Sega CD Mode 1 support functions for SGDK
Emulators generally don't handle things like Mode 1 since it wasn't used by anything commercial, so it was of no interest to emulator authors. It's like CD32X emulation - not something emulations handle. This is more a real hardware thing. Yeah, but finally Kega can be used for testing if you do no...

Re: Sega CD Mode 1 support functions for SGDK
Now i see this thread up, i wonder if there is any tutorial or else to make "Mode 1" (sorry Sik) work in emulators. I tried with Kega but it has some glitches that does not draw the graphics after loading the CD. It is suppose to work with Genesis plus gx, but i can not find any guide for that, so a...

Re: Horizontal Cell Scroll + Vertical Plane Scroll
Could it be that vdp hardware applies first vertical scroll and only then horizontal? If that’s the case, since there is no way to exchange priorities, I don’t think there is a solution, one of both scrollings has to be first. it is possible and i also can not find a solution so we decided to set h...

Re: Horizontal Cell Scroll + Vertical Plane Scroll
Your post is extremely confusing, not sure I understood it at all, but let’s give it a try. You can only scroll 28 tiles because that’s the max resolution on NTSC (28 * 8 = 224). The questin was if it is possible to make properly a horizontal cell scroll when the vertical scroll is moving. Horizont...

Horizontal Cell Scroll + Vertical Plane Scroll
I come from this topic but i do not know very well how it works and if the same applies to horizontal scroll: http://gendev.spritesmind.net/forum/viewtopic.php?f=22&t=737 In short: i have a cell (tile) scroll for a 36 tile height background. When vertical scroll is 0, then the background horizontall...

Re: DMA Fill with autoinc 128
See official documentation for an explanation; see SGDK code implementation for a solution. Fill basically works only with bytes when transferring, so both bytes of the map have to be the same; this will only work if you intend to use the very first tile as a substitute with all flags to 0 (everyth...

DMA Fill with autoinc 128
Hello mates. I think what i wanted to do is not possible due to how DMA Fill works, but i want to ask you before definitely discard that idea. I want to clear an image in a plane, column by column. Then my first thought was to do a DMA Fill of 0s from the corresponding plane nametable pattern coordi...

Re: Help scale and rotation sega genesis
Some time ago we made some tests with scaling and rotation, and as Sik said, it is very very expensive. Anyway, i you want or need to make some basic stuff in intros or something like that, we used this guide with as much optimizartions as we could: http://www.drdobbs.com/architecture-and-design/fas...

Re: Fork of DMF2ESF (Deflemask to Echo converter)
I hope someone can help us. We need some stuff to convert from a tracker to Echo, and Deflemask + your converter seems to be the best chance. Hi. I made an app to convert DMF to Echo's format. It's call "DefleMask Convert" and it's in the Tools section. You should try it. Thanks for your work mate,...
