The Glenn Thread

[Vehek]

Only works on expanded roms because it puts the graphics in expanded space. If I used an unexpanded rom as the base of my patch, I'd wipe out everything in expanded space. (At least that's what happens with patches made with WindHex; I don't know if Lunar IPS does that too.)

I originally did my hack on a Crimson Echoes rom before reproducing it on another rom, and I couldn't find any free space large enough within the unexpanded space.

Thanks. It's exciting to see him walk and stuff! Is anyone keeping track of how many frames Frog has in total and how many of them we have "Glenn-ified"? We wouldn't want to have some frames lost in the topics or something.

Hey...concerning Vehek's last post, are we doing this on a fresh ROM that will later be able to be moved over to a a rom of our choosing?  I thought we were totally replacing Frog so we shouldn't be using expanded space......(though frog is shorter I suppose....). 

I double Chrono's question about total tiles vs glennified tiles

The Glenn OW sprites makes the OW sprite packet no longer fit in the original slot. So I had to move it into expanded space to make it work.
I think the biggest problem for Glenn is that the game doesn't seem to work with re-pointed PC graphics.

[Agent 12]

Is the reason it doesn't fit because Glenn OW  is larger (not byte wise but sprite wise) then Frog OW?

[Vehek]

Yes, it's because Glenn's bigger. It doesn't compress as well as the original graphics packet.

Technically, I don't have to put it in expanded space, but as I said, I originally tested it on a Crimson Echoes patched rom,  so all the free space big enough in the original rom was already taken. I used the same offset when I made the patch using an unpatched, expanded rom.

[Agent 12]

So Vehek, you mentioned the biggest problem was the pointers, is the problem "figureoutable" or is it impossible to do this?  If it is I would like to make this a bit higher in priority, it's our shock and awe.

Repointing graphics does work but...only halfway.  There's some other pointers or SA that is missing if you repoint it somewhere else.

[Vehek]

I've looked into this, and the game is programmed to only load the PC sprites from the original banks they're in.
The important part's like this:

Load graphics bank value into accumulator.
Subtract $D2 from accumulator
If accumulator is 0, go to bank $D2 loading code.
Subtract 1 from accumulator
If accumulator is 0, go to bank $D3 loading code.
Subtract 1 from accumulator
If accumulator is 0, go to bank $D4 loading code
Bank $D5 loading code follows

Ehhh...How lame

[Vehek]

Any progress?
I'm feeling worried about whether some of the sprites (ex. climbing) can fit into the 4 tile groups.

[Agent 12]

Unfortunate this is one of the few areas where I am pretty useless I wanted to make an animation changer like chickelumps but with a gui but I couldn't load the graphics correctly and thought my time would be better spent on techs and coding for the time beings

Could TheMage help with the spriting?

I'll send him a PM.  I was trying to weed out some people by asking them to do that little challenge in kajar (where they successfully replace the baloon sprite).  There was like a 2 week span where I added alot of people to this forum and they never did anything....

Everyone seems to be able to sprite until we ask them to haha.

Maybe they steal others people art and claim it as theirs?
