Re: Video Game Consoles with games stored in single-sided cards

VideoBrain Family Computer, Atari Lynx, and PlayStation Vita also have single-sided cart edge. So does PlayStation 2, as the console can load suitably signed software from the Memory Card (8 MB) except for the last revision that can't play Free McBoot. And if SD cards count, so do the USB flash driv...

Re: Anti-spam suggestion

These off-topic advertisers are trying to make links from pages with a decent PageRank value to pages on their sites in order to improve their sites' ranking for generic search terms. To them, whether these sites are in the same language matters little so long as they pass link strength. In theory, ...

Re: Need help with editing text in Pizza Pop.

Many games with a lot of text do use compression. Other games just use a character encoding that puts letters of the alphabet other than at their ASCII code points. For the latter, you'll need a hex editor that supports a "table" file, and you'll need to use a relative search to find this table. You...

Re: Witch n' Wiz

A 64KB CNROM can switch between 4 8KB CHR chunks, and UNROM uses switchable 16KB PRG chunks with an 8KB CHR RAM chip. So, by switching between the two: you could mix and match this functionality? Yes. Also, you're implying if a ROM boots in CNROM mode from the menu, the second 32KB chunk of ROM is ...

Re: Using slow ROM for new games?

Just a conjecture: WRAM's B bus port can be written with a fast cycle because there are guaranteed not to be fast writes in consecutive CPU cycles. WRAM's B bus port can be read with a fast cycle because there are guaranteed not to be fast reads in consecutive CPU cycles, and setting the address pre...

Re: Using slow ROM for new games?

Probably. Using a 16-bit bus would likely have made the cartridges wider, and it might have caused the memory controller not to fit on the same die as the 65816. Spilling the memory controller onto another die might in turn restrict PPU capability for cost reasons. Compare the Mega Drive/Genesis VDP...

Re: Super Mario Bros.: Why all the floating money?

Williams's Smash TV (1990) has currency and prize boxes on the floor worth points, as well as keys to enter the Pleasure Dome. (In the early revisions of the arcade version, the Pleasure Dome was still under construction. A patch unlocked it.) Virgin's Cool Spot (1993) doesn't use sprites. It uses 7...

Like FamiTone2/FamiTone4 and Pently, GGSound has a converter from FamiTracker's text export format.

Re: Emulator with disassembly capability

A code and data log (CDL) is usually the same size as the ROM file. A trace logger, by contrast, makes huge files because every instruction appears in the log as many times as it was executed. For (say) a wait-for-vblank loop, this will be quite a few.

Re: List of games that use power-on state to seed RNG

"NO BOY! NO DEMO!" comes from Demotronic by Megaboys . I've been told in the gbdev Discord server that its emulator detection is just whether or not wave RAM ($FF30-$FF3F) can be read while a note is playing on the wave channel. A Game Boy returns either $FF or the currently playing pair of nibbles ...
