Re: Sharp Nintendo Television

Sharp also apparently owned the "Famicom" name at the time, which is supposedly why Nintendo always called their products by the full name "Family Computer" rather than the name everyone actually used, while Sharp's Famicom variants all used the abbreviated name (even the FDS BIOS' screen were chang...

Re: Textured raycaster on the NES

Very impressive as always with these raycaster demos. But I also like the textures of the walls.

Re: Questions about NES programming and architecture

Shadowgate and Dejavu for NES, Shadowrun for SNES and many 16-bit sports games all got translated to Swedish (video games were more popular in Scandinavia than the rest of Europe at this time). NHL '95 for Mega Drive even got remade with the Swedish national league. But generally games were in Engli...

Re: Questions about NES programming and architecture

Such details was probably not so strictly defined right from the start though. For example on later systems Nintendo always required licensed games to have some way to pause the game, usually using START button. But on the NES there are games that doesn't do that, including Nintendo's own Punchout. ...

Re: Questions about NES programming and architecture

Thanks I fixed the mistake. In Japan I think they could legally prevent unlicensed games for the Famicom, but not anywhere else. The NES got the lockout chips though which somewhat prevented both unlicensed games and cross-region "grey" importing. There were Japanese-made unlicensed games as well th...

Re: Questions about NES programming and architecture

Makes sense, I guess if the crash could happen in North America the same thing could happen in Japan as well. Besides Nintendo knew they had people that could make quality games, what with the success of arcade games such as Donkey Kong, the Game & Watch line and even their earlier Pong clones. Nowa...

Re: Questions about NES programming and architecture

So the decimal flag exists and can be set or cleared, but it has no effect on the decimal mode circuit which is always disabled due to the 5 removed transistors. There not much reason to skip a CLD at the start of your homebrew though. In interviews with Nintendo it sounded like Ricoh convinced Nint...

Re: How can I see the text of Captain Tsubasa Vol.II using an hex editor

Hex editors specifically made for translation hacking such as Thingy supports custom character encoding tables, which may allow you to see kana in the text field once you have figured out the encoding and made a table for it. Windhex32 supports character tables and can display Japanese characters.

Re: Wonderswan 2003 extended banking register width

I'm also interested in a minimalist devkit. WonderSwan seems to be a system that people code in C for (or is that mainly WonderWitch homebrew?) so an assembly alternative would be great. But I would probably need some minimalist set of tools and quick-start guide to get started. Neo-Geo Pocket, Wond...

Re: How did they flip background tiles in Final Fantasy 3?

The most accurate SNES emulator is bsnes/higan, but Mesen-S has caught up quickly, is probably easier to use and may have more useful tools (Mesen is one of the most useable and accurate emulators for NES). I wouldn't use Zsnes nowadays (although I used to find it great), and probably not Snes9x if ...

Re: Questions about NES programming and architecture

The FDS RAM Adapter is just a cartridge expansion device, and technically no different from any other cartridges from the Famicom's point of view. There is a BIOS ROM which is somehow booted from instead of the PRG-RAM. Not sure how it works. I also believe that what killed the FDS is the fact that ...

Re: About 6502 common syntax standards

He is adding HuC6280 functionality to ASM6. I like ASM6 a lot and think it's a good idea to expand it for other architectures, although I don't have any problems with PCEAS. PCEAS/NESASM is indeed more powerful than ASM6 and with the modern updates it's much more useful and less annoying than it use...

Re: Questions about NES programming and architecture

Looks good. The PRG MEM would normally be ROM which is booted from since the NES has no internal system ROM, but I guess there are people that makes working ROM-less cartridges just for fun.

The DMA controller is also in the CPU chip I think.

Re: Questions about NES programming and architecture

Here, uh, something like this would be cool. Maybe just, you know, less terribly drawn. I think it's pretty good. Only complaint I have is that you use the same term for the backdrop and the background. The red palette entry is the normally used backdrop colour, the two purple ones are the normally...
