Re: Chuckie Egg

Here's a just-about-final version of Chuckie Egg: ChuckieEggDC There are still a few outstanding bugs on the Dreamcast: - Sound on the first screen doesn't play; - Tune on the title screen cuts out half-way through; - Scroller is a little jittery on the title screen; - Tune doesn't play when the pla...

Re: Chuckie Egg

Thanks!

I thought about redoing the artwork, but in the end I stuck with graphics from the original game for the nostalgia factor.

Chuckie Egg

Here's a beta version of a new remake of Chuckie Egg I've been working on for NDS and DC: ChuckieEgg .bin and .elf files are included in the archive. There's still a bit of work to do, mainly on the presentation side, but the game itself is fully playable. This remake is based on the obscure Dragon ...

Re: Ordered a broadband adaptor; what's next?

Finally got around to testing it out. It works! The 1st_read file produced by building dc-load works fine on the SD card adaptor, so there's no need to burn anything to CD. I didn't realize I'd get console output too. Neat!

Re: Ordered a broadband adaptor; what's next?

I got an almost complete-in-box BBA for $150 plus $11 postage from eBay. Prices ranged from $130 (no box, horribly yellowed) to $300 (like new, shipped from Japan some time in the next few months). On the one hand I'm horrified at the thought of spending $160 on an ancient 100Base-T network card. On...

Ordered a broadband adaptor; what's next?

I've ordered a broadband adaptor. What else do I need in order to start using it for development? How do I get it set up? (Preferably info for OSX, but Linux would do too.)

Re: HankyAlien

ant512, care to update the first post a bit to make it look more like a newspost (maybe describe things a bit and include a screenshot or two)? I'll go ahead and move this over to the News forum if you do. :wink: Done! I'm glad to see you got things working after a few early growing pains. Testing ...

HankyAlien

Thanks to various folks on the forum, I've finished a Dreamcast version of my Nintendo DS homebrew Space Invaders clone: http://simianzombie.com/media/2016/10/13/HankyAlienDC1.png http://simianzombie.com/media/2016/10/13/HankyAlienDC2.png It's a fairly close approximation of the original arcade game...

Re: snd_sfx_play_chn() causes sounds to loop

Real hardware works fine; it's an lxdream bug.

Thanks everyone!

Re: snd_sfx_play_chn() causes sounds to loop

I've created a minimal example here (source/makefile/build script/romdisk/elf included): soundtest.zip The first sound plays OK. Then pause for 2 seconds; when the second sound plays, it *also* replays the original sound. Then the volume steadily increases as the system is overlaying multiple copies...

Oh, KOS only supports 16-bit WAV files. Makes sense. Now to figure out why the sounds are looping?

snd_sfx_play_chn() causes sounds to loop

I've got a bunch of 16-bit, mono, 11KHz RIFF-WAV files that I'm trying to play with the snd_sfx_play_chn() function. Everything works except the sounds loop until another sound is played on the same channel. Any ideas what's going wrong? [EDIT] If I switch to snd_sfx_play() then the looping stops, b...

Re: Testing .elf on real hardware

Is that real hardware or an emulator? Is the SD loader a custom BIOS?

There isn't any background music other than the "boop" sounds played when the aliens move.

Looks like the sounds are playing at double the correct speed...

Re: Testing .elf on real hardware

Thanks! Here's an update: HankyAlienDC Changes are: - Switched to store queues instead of writing to VRAM directly (much faster); - Enabled sound (though I've only tested it in lxdream, where it sounds horrible, so hopefully it sounds better on the real hardware); - Restored the correct color palett...

Re: Testing .elf on real hardware

Almost nothing Dreamcast-specific. I use the Maple functions for polling the joypad, a waitvbl function, and vram_s[] for writing to the framebuffer. Everything else is a homegrown set of libraries that gives me a reference counted, object oriented MVC GUI framework in C that compiles for Nintendo D...

Re: Testing .elf on real hardware

Hmm; on a subsequent attempt using sh-elf-objcopy -O binary blah.elf blah.bin it works fine in RC4. Weird. But, success! Here's my first hastily cobbled together Dreamcast game: HankyAlienDC It's still got a few issues to sort out (I forgot that 320x240@60Hz really means 320x200@60Hz, so stuff on th...

Testing .elf on real hardware

I've got this far in my quest to get a game running on the Dreamcast: - Installed the KOS devkit (OSX and Ubuntu versions; thanks bogglez); - Installed an emulator (lxdream); - Re-acquired a Dreamcast; - Acquired a serial port SD card reader (plus DreamShell RC4 and beta 4, and a compatible SD card)...
