"should continue to read sector during your data transfert. "
Yeah, of course, i'm already doing this...
I don't stop reading (exept if i loose a sector).

So... i don't know where is the real problem :/

I see... but i load 128KB imediately (no wait, no sector dropping), i think my lag comes from the gap to wait PCM sample to finish (so the cdrom drive pass the next sector and need to go slighty back)... Since it happen every second, i thought it could be ok.. It is not :/ I think DMA is just to get...

Well, in fact, segacd bios have a seek function... but in my case... i really wonder how i can use it... Each time i tried to use it , it randomely crashed the thing... :/ You know, I read data in streaming. Well, i'll try again. I'm just disapointed that nor Kega or Gens emulate CDROM seek/read tim...

You may find here some samples and asm toolsuite
Good luck

Hi :) I have some troubles to reach maximum reading speed on megacd hardware. It is theoricaly situated around 150KB/second. However, even if emulators allow a such fast rate, on real hardware, i cannot barely go over 96KB/sec. :'( Some FMV games are supposed to be 100-150 KB/sec bitrate so I wonder...

Hi,

There is no way to add a ram to this megacart hardware... sorry.
An idea would be to add this

to the joypad port 2...

And how many ppl would buy it (it would cost 30usd, quick estimation) ?

hi "I definitely want 32x support," Megacart supports 32x roms. And it is cheaper than MDpro64... However, it don't support SRAM nor 32M games. I personnaly find megacart quite usefull for segacd dev because i don't mind converting my DEV isos to my segacd region each time i build a new one... "Any ...

Funny clip, i have it somewhere on my HD Wink Impressive image rate for a such big window ! And the video quality is always getting better Smile Are you refreshing the entire image at each frame ? Are you setting top and bottom border as blank area to maximize the VDP VRAM write capabilities ? Than...

Yeah... and there is no way to resample with Z80? I mean, playing a 4khz sample on my sound card is pretty okay... 8khz is almost good :) About the 4bit samples, no clues why i get a "CHHHHHHH" background by removing the 4 lower bits of a 8bit sample? Thanx for your answer. Quickman : Some games use...

Left : Original - Right : EQX PRO8
Improving again my codec
I think i fixed the reading slowdown on real hardware, i'll test it soon

Enjoy 28MB of pure pleasure ;P

:arrow: I have a question :) I figured out that some games (and even late games) were Z80 driven for BGM and 68K driven for SFX... how it is possible? I mean, how they did to fill correctly (at good speed) the DAC from 68K and have a 50hz game running? :arrow: I have another question :) I tried to m...

Hi,

I checked again, I don't have font problems with kmod. And i'm running on win98SE.
My problem was because you compiled the cdrom driver badly or something like that, you remember?

Btw kaneda : your VRAM scrolling is way better

Woah :D Crazy particles :) Héhé, i wish there could be a use for those crazy effects, héhé the multipart demo? ;) I was really impressed by the speed... Top of that you are using a framebuffer, well done ! Atm , the only "3d" effects i released is the SuperX MD :P Funily, it is 20fps only... haha, I...

Same, i use C only... But for mad things like segacd bios jumping or rom header, i had to use ASM.

And Pascal may confirm that GCC generates a pretty fast code, probably as fast as ASM for average code, isn't it?

I use Pedit to generate my palettes
It allow very fine palette generation but its a bit rubish to use if you just want to do a quick/not important thing.
