Re: What is your process for creating graphics for the SNES?

On the topic of pixel programs for the Amiga, don't forget Brilliance! It lets you set the bitdepth to match the SNES (32K colours) or Megadrive/PCE (512), as well as custom page sizes, like 256x239, etc. Brilliance has multiple undo levels. As for aspect ratio, back in the day, a few CRT monitors h...

Re: Deflemask player for PCE

Nice! It's good to see a game- or demo-oriented assembleable tracker project going for the PCE. Not that I'm a musician or anything.

Re: Hori Game Repeater

I had the Game Repeater back in Canada, and yes, I thought it was really weird... and of limited use. * Won't work with games that have some kind of randomness In theory, when you press the large button to reset/replay, the Game Repeater resets the Famicom, so the CPUs should be synchronized and the...

Re: PC Engine / TurboGrafx open bus

I'm guessing that the TennoKoe bank has address decoding logic that monitors the upper addresses, read/write line, and some of the data lines; and which activates / disables the presence of the Bank RAM depending on those accesses.

Also, the TennoKoe card has to access bank $F7 to map in the BRAM.

Re: PC Engine / TurboGrafx open bus

About the TennoKoe Bank, all 4 save slots are in a single 8K bank. The access method: Okay, I just confirmed with my program, PCEMon, and a Ten no Koe Bank card on a PCE/SuperGrafx. Write #$68 to $0000 in bank $68. Then write 0 to $0000 in bank $78, then write #$73 to $0000 in bank $78 three times. ...

Re: Pro Action Rocky cheat device for Famicom - reverse engineering

The Action Rocky is indeed mysterious and interesting. It can be fully set to English, but I don't know if there's a menu option anywhere. Instead, if you dump the entire Rocky ROM, and change hex location $1CA91 (raw, no iNES header) from 01 -> 00, all the menus will be in English. If you figure ou...

Perhaps Kirby's Adventure counts?

Also, off the top of my head: Remote Control, Gimmick!, Cocoron, parts of Panic Restaurant, and T&C Surf Design

Re: We need a better name for "Adventure Games."

2600 Adventure is named after the adventure game Colossal Cave Adventure , based on the original adventure game Adventure . They're one and the same. If you wince at all the repeated use of that word you find ill-defined, then that's my point: it's inextricable at this point from the genre, its hist...

Re: We need a better name for "Adventure Games."

The first adventure game was literally called "ADVENT.EXE" ie: "Adventure". Sorry, dudes, give up. This is not the hill you want to die on.

Re: Has anyone tried to obtain an "Official Seal" from Nintendo for their game?

Nintendo had an even tighter grasp on the supply chain in Japan during the NES and SNES eras. Nintendo franchised game stores received at least 10 times as much stock as independent stores in exchange for letting Nintendo dictate pricing, game placement, signage, etc. Yup. Independent shops signing...

Re: Sharp Famicom Titler

I wonder how the Graffiti-like interface works? Nothing else looked too unusual. There are two ways to "free-form" draw on the Titler. The first is when you are using Famicom games, the stylus pad and the buttons on the side are the only ways to "interact" (if you can call it that) with the Famicom...

The power board perhaps also needs a quick fix. Shown here: http://forums.nesdev.com/viewtopic.php? ... 98#p129898

But yeah, if a disk doesn't LOAD, then it's most likely losing its data.

Re: FAMICOM CONTROLLER IN TWIN FAMICOM

Try turning off all savestate / Up+Select to reset, etc. functionality that the Everdrive provides. Perhaps its ingame controller reading is interfering with or blanking out the expansion controller's data going to the game.
