Re: FDS header date fields

I see! What about the CopyRight date? Should that number be consistent amongst different revisions of the same game? If not what could that mean? From there, I assume that the "Written" date can be overwritten and changed if it was taken to a local kiosk as well, yes? Assuming the kiosk itself must...

Re: FDS header date fields

Even better! This is pretty awesome for a tool now. When it comes to the disk listing for the "Written" label it only captures the initial writing date, correct? Like say if I wrote a Doki Doki Panic using FDSStick it would have a written label that's from 1987 instead of 2021, yes? Yes, FDSStick d...

Re: FDS header date fields

OK, I've made a newer version of the Disk Lister that lets you read the disk the old way, or you can press START to put it into a deeper scanning mode, which will display more of the disk's header, as well as try to read and display all file headers on the disk. http://chrismcovell.com/data/FDListNA...

Re: FDS header date fields

I've been meaning to update my FDS Listing program, but date / disk ver. info is not accessible in the data returned by the BIOS subroutine that my program uses. I'll have to rewrite the program to access the header files by directly reading them. (So don't count on an update anytime soon.) Ahh, th...

Re: FDS header date fields

Neat! I have a great interest in this as I am collecting FDS games. Is there a way for you to incorporate this into your old "FDS Disk Listing Program" as well?

Re: FDS header date fields

Of course, that makes perfect sense. I've updated FDSList to show disk contents like this now: ------------------------------------------------------- DISK 'DRM ' Side A Files 7 Maker $01 BootID Lim. $0F Disk/Game Ver. 2/0 (C)/Written 1986.11.26 / 1987.09.15 -----------------------------------------...

Re: Do colored borders bother you?

Well, when designing your graphics, you made a choice as to what colour 0 had to be, right? It had to be the single colour that needed to be in all 4 BG palettes, and that was the most important reason. The borders being that colour are just a follow-on effect from that decision and have to be lived...

FDS header date fields

Hello, all. Recently I thought I'd update Marat Fayzullin's FDSList once again, and add a readout of some more of the data in the FDS disk header. That got me interested in the two Copyright/(Re)Written date fields, and the quirky date format some games have. So, most games are "supposed" to have a ...

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. ...
