In a while I'll try to do some effect based in Hblank. First of all I went on analyzing some other code, and this is the code that Sonic the Hedgehog uses for reloading the palette for the water:

DrawWater:
move #$2700,sr
tst.w (f_hbla_pal).w ; is palette set to change?
beq.s @nochg ; if not ...

Hello.

This time I'm trying something different for Sega CD... Keep SubCPU to process all the main engine, and MainCPU to process all I/O. For such, I have done the following: From SoulessSentinel's SCD template, I have done exactly the inverse method: SubCPU to hold all the main code, and MainCPU ...

The message itself is valid, but not the source addresses :P. I got access to my Desktop PC again where I have a modded version of Genesis Plus GX for retroarch with error logs enabled, and although my code mistakenly indeed do write at those bad locations, the bad code was from a much earlier ...

So, I decided to give a try to some special Gens KMod debugging features, apart from the typical memory viewers and such. After enabling a few of "Spy strange behaviors" features, I get the following warnings:

Spy : 202CBC want to write a Word at 00BFFFFC
Spy : 202CBC want to write a Word at ...

I'd like to approach this situation to ask for something I wanted to know since the start: How are the CDDA decibels read? I must have being missing something, but I really can't find anything about.

I'm very confused about when do H-int and V-int happen. Please take in consideration I put most of VDP writing code on V-int section.

Does the V-int code run before, or after the frame is drawn? If happens after, then does it mean that what we see on screen is 1 frame delayed? :O
And, does the H ...

Okay. Here are the files I have built:

-Wii version
-Game Cube version
-Linux-based RetroArch version

I'll try compile the Windows-based RetroArch version (the .DLL module) as soon as I get free from the pile of work ...

Hmmm... the truth is that I don't use a Windows OS... and I don't really know how to edit the libretro's makefile to output a DLL... I use Ubuntu, and by default a .SO file is generated upon build. I just don't know how to let it build a .DLL file, but I may check it some time. What I can do however ...

Yay!, as soon as classes finished today, I RAN to my PC to try it up. Works perfectly.

Thank you!

EDIT: A remainder, if anyone else try it: some "for" blocks gave me build errors, to fix I put "int i;" just before them.

Heh, sure =D. Though that's the only "big issue" I have found so far (apart of not emulating the illegal addressing issues, but that's usually something the ASM compiler I use do take care of :P ). I have already tried to insert the check in both KMod and GenGX+ source codes, but everything went on ...

not to be negative (it's the least I currently want), but a strong problem Gens still have is that it shouldn't allow access of WordRAM from both processors at same time (It's my biggest issue currently). Sometimes I see no better way than trial-and-error against real hardware

Time for a goofy question now... but here it goes:

Years ago, while trying to learn the basics of the console, I had bugs, lots of bugs. But in a single ocassion, I made it bad enough the game didn't crash, but the emulator. Until today I haven't been able to do it again; I don't remember how I ...

Thanks a lot! =D

Sure. My question is, how much of the image is cropped in such case?

I wanna be sure if I can draw the HUD for my game and put it at the very bottom of the screen with no problems...
(as stupid as this question sounds XD)

EDIT: Seems like a new forum has been introduced, and I should have posted this thread there . I'm sorry! *facepalm*

As for NTSC hardware, as far as I know, adapter renders four border to screen's four edges, while the "graphical" part is stored at the center...

now my question is, are those ...
