Originally posted by FreeDOS Emulators and general don't rely on info from the header to generate gameplay, as far as I know. They just provide some very simple information, almost all of which is likely already embedded in the rom itself (things like SRAM size, the ROM size, FastROM designation, etc.) Look around the $7E00 region (ish) and things like the game title, publisher, etc, should be there. Of course you'll have to read a document to know how to decipher some of it. See, I personally don't care about copier headers at all, so zeroed data suffices to just provide that file size adjustment to make ips patches work. Unless someone writes a program that is hardcoded to read critical data from there, they really don't matter. If you actually have a FIG/SMC/SWC, zeroed data is probably a bad idea to insert :x. edit: @Techokam - My comment was not directed at Fu, but rather as a case-in-point of the debate going on in the open source thread in the Normal Romhacking forum right now. I certainly respect FuSoYa's whishes to not release his source, that is his business. But there's no denying that it would be helpful to have for any serious SMW hacker.

Although, it's lame to have it scaled to modulo 10. They should have output the digits in base 12 and use that instead (b/c there's liek 12 notes duh) |

| They don't usually show up.
I've heard this is true, though I've never had a speeding ticket. |

| @Hyperhacker:
That gamepad sounds like an Ascii pad, or something similar. I had an Ascii Pad for SNES but I burnt out the A button's connection by leaving the autofire on for hours while powerleveling to ** in the Black Omen in Chrono Trigger. Basically had it preset to use Falcon Hit with Gold Studs equipped, and got 2300 exp a pop for this one battle. all I had to do was run back and forth to the screen to get the battle to reappear. I can't say I was surprised that it burnt out  . |

| And that post of yours was pointless.
Sometimes you just have to wonder if people are attempting to appear ironic. |

| An Ips patch is only safe here if it doesn't contain copyrighted material, however. | |||

| Duck tales was indeed the shit. Nearly every Disney related title on the NES was the shit. Even the Little Mermaid was enjoyable (that was my sisters but I still played it. )
However, the original poster mentions some games which I found to be quite subpar. e.g. any Ren and Stimpy game EVER. I can't think of a Simpsons game on NES or SNES that I have enjoyed... Bart Vs. Space Aliens, Bart Vs. the World, Bar'ts Nightmare, I found them all to be lacking severely. Simpsons Road Rage for GC was pretty enjoyable, but even that is a ripoff of Crazy Taxi. Let's not forget games based on Beavis and Butthead. The thing is, to make a game based on a movie/television show, I think the actual movie/tv show has to have some elements of adventure, something to make it worth using as a video game subject. All those shows, Duck Tales, C&C Rescue Rangers, Darkwing Duck, etc, had elements of adventure and danger to them. A game based on Ren and Stimpy is likely going to be full of stupidity and stock sound effects and gags from the show. And who ever played a game to see comedy you've already seen executed 100 times better on the actual show? And correct me if I'm wrong but wasn't there a SNES game based on Beethoven (the family movie about a big dog). Recipe for a yawn. So yeah I think it would be cool to have more games based off of shows, but it would have to be the right kind of shows. And even that's not enough b/c you have to think of fresh situations and gameplay elements to make it fun. |

| While I've been mostly able to follow SPC instructions either from finding a source or just intuitively, TCALL is bugging me. Since the documentation for the SPC's instruction set is poor, I was forced to consult a pdf reference manual for the GMS81508B (what an ugly name) Microcontroller. It's apparently somewhat similar in design, along with a few other chips I looked at. It says the following about TCALL:
Table Call (TCALL) causes the CPU to jump to each TCALL address, where it commences the execution of the service routine. The Table Call service area spaces 2-byte for every TCALL: $FFC0 for TCALL15, $FFC2 for TCALL14, etc., as shown in Figure 8-7. The opcode is X1, where X is the vector* to use. (01, 11, 21, ..., F1) Basically it looks like a software interrupt similar to BRK on the 65816. So far in the code I'm examining (The N-SPC) I have not hit a TCALL instruction. Here's what bothers me - $FFC0-$FFFF is used as the bootstramp ROM on the SPC-700. So it won't contain any vectors in that address space. So either 1. Nintendo didn't intend the SPC-700 to be used with this instruction or 2. The table for the vectors is located elsewhere. Entirely possible since it's a totally differen't chip from the GMS81508B. * In this context, vector means a pointer to a special routine. |

| Well yeah I was referring to console games, not arcade. That Simpsons arcade game was just total ownage. If I could own any Arcade game, it would probably be that. *checks ebay*
yay Now give me $900. (edited by MathOnNapkins on 02-03-06 10:39 AM) |

| @Sickness: no. Still waiting to see Final Dest. 1 and/or 2. Gonna be a long wait.
I saw this movie, and I liked it on a number of levels. Movies with lots of gore and tension really get me going. I didn't like the "hero" (if you will) at the start of the movie. I guess that was the intent, b/c you start to see that he actually gives a damn about other people, whereas earlier in the movie he was made out to be a partygoer itching to get drunk and laid. But he becomes strangely a sympathetic character about 3/5ths into the film. The movie has convinced me to never visit Slovakia or pretty much any place in Eastern Europe if I ever go abroad.  |

| The CPU communicates with the SPC via 4 I/O ports, not interrupts. .
The SNES is a lot like the NES, right? In the area of sound processing, not even remotely close. No offense, but I'd really like an answer from somebody who has coded or disassembled SPC code before. |

| You know if you had a copier you wouldn't have this problem. Oh noes lost my rom. *DUMPS* | |||

| Yes, as long as it doesn't contain anything stolen/copyrighted. Public Domain Roms are just that. | |||

| Uh... i played all 4 discs of FF9 on epsxe about 4 years ago. What exactly was the problem you guys had? The version really hasn't changed since then much either. v. 1.6 or 1.62 or something. | |||

| Ah, thanks for the confirmation of that. And by disable the ipl rom, you mean just write over it later on via the SPC itself? I mean, you can't do it during the initial data transfer b/c that is what is loading the data in the first place. And is this true what Goplat says about $00F1?
This is the best documentation I could find on that register. It's from SPC.log, from neviksti's starter kit, I believe. $F1 SPCCON1 bits 0-2 timer enables (1=on), bits 4-5 are I/O port clear bits (11=clear all) Doesn't even mention bit7, or bit6 or 3, for that matter. The NSPC engine writes the value #$F0 to this register before starting its main execution loop. (It would of course happen again once you loaded a different bank of SPC Data.) Why would the programmer send data to bit 6 and 7 of register $00F1? The NSPC can load new data itself without using the ipl rom. Actually, when it does load new data through it's own routines, it does MOV $00F1, #$31 at the end, which makes more sense. |
