Example of meta-tile drawing (4 tile x 4 tile) blocks :START SCREEN

Recommended Posts

Just wanted to give a quick example of how the " TECMO SUPER BOWL" text positioned in 4x4 blocks

 

If we go to 0x05056 in the rom we get the following data:  A5 b6. This is a pointer to the data sequence. Flipping it and andding 0x10 for the ines header offset we get 0xB6B5.

 

Since 0x4000 is loaded in as a $A000 bank. B6B5 points to $56B5

 

At 0x56b5 we have the following sequence

 

20 76                                    ; These first two bytes set which 0x0800 size banks from the CHR section of the rom (0x40010 onwards in 28 team)

                                             ; we will use that contain the tiles we need

02                                         ;  This byte tells us which bank will be used to draw the 4x4 tile sections 

20                                         ;  This byte sets our background pallete index

03, 06                                   ; These two bytes set (# of metatile rows, # length of the metatile sequence) 

09                                         ; this byte sets the starting location for the metatiles (refer to the image below) 

42 43 44 45 46 00                ; these are pointer indexes to draw the metatiles

47 48 49 4A 4B 4C

00 4D 4E 4F 50 AB

 

I made a spreadsheet helper to make things clearer refer to the image below

 

Going through the first line

 

42= draws part of the white S

43= top part of the S and part of the U

44, draws the red TEC and part of the m as well as part of the top of the U and P.

      Spurred on by a suggestion from Tecmo Turd, I've decided to take a look at giving the 32 team Original Tecmo Bowl (no Super here) a graphical touch-up, starting with the title screen. 

       

      There's precious little info on OG Tecmo here, and I have a question i was hoping someone (with greater hacking knowledge) could answer: 

      Would it be possible to shift the title screen cursor down a line or two? I can't seem to find where it's being drawn in the hex. The rest of the title screen starts at 0x006686 in the 32-team TB rom. I believe it's the same in vanilla TB. 

       

      I ask because moving the "1 Player / 2 Players / Coach" text and accompanying cursor would give me more hex space to draw a better title screen.

       

      I'm keeping notes on everything I do and will post info for those interested as we go along.

      Any interest in revising the large helmet template? Very few players use the classic circular shell anymore, choosing instead the more sleek (and protective) Revo Speed. I mocked up what a Revo Speed helmet would look like on the team data screens. I've included the "single stripe" and "Double stripe" large helmet templates. Yea? Nea?

       

       

       

      The facemask is just a stand-in at this point.

      I needed a high-res version of the text from the TSB title screen, so I GIMP-ed one up using paths.  It wasn't difficult, but it was time-consuming, so I figured I'd post it up here in case anyone has use for such a thing. 

       

      Note: The image has a transparent background, so it's a little difficult to see the words "Super Bowl."  It will be easy to see in any image editor.

      I've been noodling around with the graphics on TSB for Sega using Fatilety.

       

      You'll notice, I've given the Pitch a more "old-school," classic feel.  Also, it looks as if it's actually been played on.

       

      I changed the Chain Crew.

       

      I've also modified the ball, so that it accords with the much rounder football used until (I believe) the 1950's in the NFL.

       

      If I could, I'd have rather wanted to place the Goal Posts on the Goal Line as per their (logical) placement in the NFL until the 1970's.  Alas, I couldn't find a way.  I was, however, able to change them to the traditional, H-style posts . . . or, at least, came close to making it appear to be so.

       

      There are some glitches in the alignment of the Yard Lines (e.g., at the 50- and 35-yard lines) based on that fact that they placed the NFL and Tecmo logo's on the field, both of which I removed.  I don't think either is too noticeable.

       

      I think, I might try my hand at the SNES version and do the same.  Though, I must admit: I like TSB Sega better.
