    How I may change the Horizontal video scroll manually?


    If you dont understand me, here's what I'm needing:


    I need move horizontally the Plane A, but without adding anything to FFF700, or updating the scroll table. I just need to move that.


    I tried to move the screen vertically in the splash screen code, changing values in FFF616, but it not work on normal levels.


    ------------------------------


    What EXACTLY does the ANDI command?



    andi.w #$00E0,d0 ; keep in multiples of 20 and in range of 100 (100 / 20 = 8)



    You know, as result, I'll obtain a $8. So, I think that if I change the E0 to F0, will be 100 / 10 = 10, but it dont worked correctly.

    To understand how the AND command works, you have to imagine the values in bits. Here's an example:



    Code:
    Value:  0110 1100 ($6C)
    
    And:	1100 0110 ($C6)
    
    -----------------------
    
    Result: 0100 0100 ($44)
    Now, what this does is taking the bit of "Value" and compare it to the bit which is right below it. If both bits are set to 1, the result is 1 as well. Otherwise, it is ALWAYS 0.


    So to put it in a nutshell: Only true and true is true.

    I was porting the Sonic 3 driver to my Sonic 1 hack with the guide from Sonic Retro that I used and completely followed the instructions with. The link is right here:


    http://info.sonicretro.org/SCHG_How-to:por...iver_to_Sonic_1


    But when I got to the Sega Screen, the game crashed on me. What did I do wrong?

    Could you give us some more info, as you may have followed the guide, but unless you did something else after, you have most likely made a mistake somewhere.

    As a matter of fact, I did follow the guide properly and did what it says. Yes, it built my rom hack. But after the Sega logo appeared, it gave me some sort of illegal instruction. If you didn't believe me, the proof will be found in the source that I have right here.

    Hope you figured this out by now. Open the built rom and you'll see what I mean.

    I want to make a video of my hack and upload it. Do you know if there are any Genesis emulators that can record videos?


    I'm using Gens. Thanks. ;D

    You should either get screen capture, fraps, hypercam, or you could get Fusion, install the video codec, and then use the built in record feature to record your demo. I would chose the later, because it is much easier to get Fusion, than to try to get Fraps going. Also, Fusion is more accurate when it comes to emulating, so you can see if there are any problems with your hack that Gens "smooths" out.

    Gens does have a video recording fork, I can't seem to find it at the moment, but i know it exists.

    Well my method for uploading "hack" videos onto YouTube is basically http://www.youtube.com/watch?v=Jt0LMqm__Gs.


    And done, but... YouTube can't for some reason upload the AVI video recorded from Kega Fusion. So, I use Camtasia Studio 3 to fix this problem.


    Load the video in Camtasia Studio 3, export the video as AVI, upload and done. Hope this helps. =)

    Considering that the Sonic Retro wiki article and its readme is as vague as can be, how on earth do you get PlaneEd to work?

    Check the topic on retro, it explains it completely. You basically have to make a .bat file for everything you wanna edit.

    I tried making bats, but they led to error reports.


    EDIT: Nvm, didn't put it in my disassembly. I wished it would've mentioned that in the readme...

    I'm editing my custom made BG in my SLZ for my hack, when I notice the tiles 375 (in hex) to 1A5 that I added are corrupted


    after I've edited them and I play my hack on an emulator.


    I think I went over the original tile cap for SLZ. Is there a solution?


    These tiles appear perfectly normal in SonED2.

    If you mean you've gone over the tile limit, you could try and reduce the amount of tiles you have. Or if you know how to work with vram, find a way of making more space, maybe changing the location of where the tiles are loading to a much larger location.

    Just to be sure, you mean the "SONIC" text, or actual sonic sprite itself?. Its not easy to edit the title text, but not incredible hard either =). Maybe I'll explain in my tutorials when I set them up. Anywho back to the task at hand, first you want to load the title graphics titlefor.bin in artnem(assuming it's the text). Then open the pallet file title, in the pallet folder. This will then load the correct tiles for the art, and pallette. Heres the tricky part, look at the tiles that appear and select one, and then at the top choose the top line with 4 tiles in it. Example:


    [​IMG]


    Boxes in purple, is where you click on them to select. So like this in steps:


    1) Select the tile, first on the left of the pic.


    2) Then select the row of 4 at the top, second purple line.


    3) repeat 1 and 2 till the end of the text and then start the next row


    [​IMG]


    Just for text you'll most likely want this as the final result. Now you want to go to file at the top, Save to image, export sprite frame. Then you can edit this is paint, when your done save it in paint, and import it back in. Save the tile graphics, and the palette and done!. I hope this makes sense. It might be worth, changing the paint palette to the title to make it easier.
