    Genesis Colour Specs?

    I think the OP wants to create authentic mock-up art. I'd say focus on coming up with a good common 16 color palette and stick with it for each mock-up screen. Worst case Genesis games look EGA. Best case like an average Amiga game. Dithering is also very important and lowering your allowed...

    Genesis Colour Specs?

    I'm not the definitive answer. Technically the great and powerful Wiki says "512 colors, 1536 including shadow and highlight mode" All I know is that each tile can use one of four palettes. Each palette has 16 entries. 1 is used up by transparency and the other 15 are whatever colors you...

    TADPCM

    Thank for the clarification! I did a check for the code and labels given in Step 4 for the TADPCM example in BEX and they are not present in any of the files in musicdemo4.7z Unless I'm really, REALLY missing the point Sega16 failed to include his specific driver a.k.a. pcm_player.asm

    TADPCM

    I've already asked the person involved in the BasiEgaXorz example but I thought I'd go to the source as well (for help). This is the post covering TADPCM use in BEX: http://devster.proboards.com/index.cgi?board=basiegaxorz&action=display&thread=768 One of the steps is to use a file called...

    How old is SX ?

    I hope "drama inducers" is a positive piece of jargon. I just left a forum where the only active member with a clue was also a grumpy troll. Think Star Trek parallel universe Chilly Willy.

    How old is SX ?

    I just discovered this place myself. For a low traffic forum it seems alot of amazing hobby developers lurk here. It's not everyone who decides to wake up and make a Sega 32x library

    Any gotchas with save game RAM?

    Well, the only service I know is gamereproductions.com and they scavenge existing commercial boards. So I would probably be working around the fact they had only one memory tied to the low byte of the bus. What do people usually call it? 8-bit SRAM? I guess I could try and make a run out of...

    Any gotchas with save game RAM?

    I'm thinking an RPG Maker concept would be possible if I can count on the typical 8k save game RAM. Any gotchas people have found out about? It's battery backed RAM so it wouldn't have the limited read/write cycles of flash. Don't see why an end-user constantly saving and reading all 8k...

    Good Code Commenting

    I hear that! Back in high school I wrote a platform scrolling engine in QuickBasic. It used Mode 13 (320x200 256 colors) without a buffer. To emulate a buffer I set half the colors black and XORed part of the screen. The scrolling was accomplished by copying a viewports worth of drawn (but...

    Good Code Commenting

    How does one comment their main program and functions? I've heard good coders have default templates to help them describe their programs and functions. As I am forced to rewrite my engine I've come up with these examples below. How do you (more savvy) coders comment your code? Is this...

    Good map section loading strategy?

    So, my thinking is, each point in my map will be a 16x16 tile chunk of landscape. I'll be using the 256x224 video mode. In order to fit 30x30 chunks of landscape plus 3 chunks around it (for the edges of surrounding maps) I'd make a 36x36 array. Basically padding the edges with data from...

    Public domain tile compression/decompression

    Thanks Chilly Willy! As usual, your advice is (as Asus is prone to say about their motherboards) ROCK SOLID: HEART TOUCHING!! For the dingle-dorks like me still using Windows and have no experience in C (beyond creating 12 errors in a 5 line "Hello World" program) grab Portable GIT here...

    Public domain tile compression/decompression

    I had pinned my hope of tile compression on a library called "Kramlib" but the two methods used are ripped from Sega: Nemesis and Kosinski. What do people use in lieu of these? Are there any examples? Thanks again for any advice

    Best/Favorate Windows Version

    Despite needing a specific order to installing patches and drivers NT4 was awesome. I had dual Voodoo2s with a dual Pentium II 450s on a 4 drive RAID. Even Zelda 64 ran nice! Windows 2000 can still run almost all the games I need without lame activation. XP is where they enforced that you...

    Good map section loading strategy?

    @ExCyber: That's pretty cool info I just watched the Classic Game Post Mortem for Pitfall. Those old school pioneers were smarter than the average bear! @Chilly Willy: Again, very cool ideas! Loading map data by object trigger is something I never thought of. I suppose I could have...

    Good map section loading strategy?

    So, I want a very large game world. I know it can be done as I've played The Faery Tale Adventure on the Genesis. How do developers handle the transition between one block of map data and going into another? All I can think of is duplicating the edges of map data from adjacent maps so it...

    Any gotchas reading tile buffer/pattern table?

    Thanks for the sanity check! I'm now starting to suspect my own map data loading code. I'm probably triggering the map drawing code over and over again thus borking the tile reading. Being a newbie means rewriting your entire engine over and over again

    Any gotchas reading tile buffer/pattern table?

    I've read several VDP docs and I don't see any gotchas. However in my side-scrolling engine I (seem to) have issues with reading tile values at the edges of the buffer. Say the screen is set up as 64x64 tiles I'd have trouble reading values at the 64th column or row. Probably chasing a red...

    Simulating Text Mode Graphics on Genesis

    Thanks for the input! Hmmn.. So, would I have to copy the tile to a separate memory location, change the background color to one I select then copy the tile back to the screen? Or, would it have to be a completely new tile since I wouldn't want to change every tile on the screen using that...

    Simulating Text Mode Graphics on Genesis

    Thanks for the sanity check There's an undocumented feature in BasiEgaXorz where the INK command can take a second parameter for a background color. INK usually only allows switching the foreground color of a tile between the 4 palettes. Pending that, yes, I might have to waste a tile layer...
