Mega EverDrive / Re: Why no compressed ROM files?
« on: December 20, 2020, 08:09 AM »
I was wondering why ROM files can not be compressed or be able to use a folder that is compressed on any Mega EverDrive Flash Carts? Emulators can do it, so is it a software or hardware issue causing not being able to do so on a flash cart? I always thought this was a bit strange & never gotten a straight answer why.
In a nutshell: it's a hardware limitation.

Technical Reason: Because the 68000 processor in the Genesis is far too slow to decompress data with modern algorithms with hardware made in 1988. Unless Krikzz finds a way to decompress the files with the ARM processor in the MEDPro cart, it's never going to happen. Even then that might not be fast enough.

Never going to happen.

I know they both use the DP-1 chip, neither of those games work. Super Mario Kart will load and have the Nintendo icon display then freeze. Pilotwings will load up, I can select a mission, but when I hit start to start the mission, the screen goes black. The music still plays but there is no picture. What am I missing?

All my ROMS are good, I've played them on multiple emulators to test.
you need have dsp files inside the sd2snes folder for them  to work

dsp1.bin (CRC32: 27124599)
dsp1b.bin (CRC32: 588279B4)
dsp2.bin (CRC32: F0221C90)
dsp3.bin (CRC32: E3B54E6A)
dsp4.bin (CRC32: CA09E176)
It's either DSP1 or 1B, not both, otherwise you black screen all of the games that use DSP-1.

It's not really an issue that Krikzz will care about, as this cart was meant for playing games and for homebrew development.

EverDrive N8 / Re: N8 (non-Pro) future support

Will the new mappers added to N8 Pro be added to the old N8 cartridge ?
Yes, just no bug fixes.

I started compiling problematic games on twitter:
Space Invaders and 65816 code works as expected because it does access hardware the same was a real SGB/2 would.

Why MSU1? Why not modify games to take advantage of the N-SPC engine provided by the SGB/2 to access the internal SOUND A B library for effects in games? Why not use SOU_TRN and DATA_SND for custom Super Game Boy soundtracks? Now that this is possible on a large scale, why not access the unused OBJ_TRN mode (which I got working a few years ago) for SNES sprites in games? Or even up the ante and access other parts of the SNES functions that were never touched by original developers such as adding mode 7 or mosaic effects, etc in Game Boy games? the possibilites are now endless. Why do we need to jump to overkill with MSU1?
Can you list them in Google Docs? It's far easier to organize and other people can add to that list.

SD2SNES is good as a nuclear fusion reactor.

I'm not sure whether he intends on releasing anymore updates to the original N8, since the recent updates have been degrading the performance of the NES/Famicom during OS operation.

Was this something mentioned on Twitter?
Judging by the change log.

The FDS bios has been removed due to copyright reasons. Super Mario Bros. 2 (FDS) World 4-4 bug has been fixed only on the N8 pro cart.

Does the sd2snes auto patch for translation or do I need to manually patch ?

EverDrive N8 / Re: Mapper for Bootleg and Pirate Fighting Games
« on: December 28, 2019, 06:28 AM »
Yeah, bump. Don't care. :)

Anyways, Mapper 83 is the Conysoft pirate mapper. More info here:

The mapper obviously exists (I REALLY don't understand why he thinks these "not exist"!), as do the other 76 in white. Hopefully more of these will be implemented in future updates for the pro and original N8 carts. The pirate ones I'm looking forward to, are the rest of the Hummer Team/JY Company mappers (116, 121, 123, 208, 209) because at least they are actually decent for what they are worth compared to other bootleg games....

NESdev mapper grid: Best information for implementing these is here, along with the Nestopia-UE source code.

the Mega everdrive X7 is better  than the Mega SD
Try again, pal

Don't know where to post this, so can a mod split this post into it's own topic, that'd be great.

Now we know why he stopped working on this update for a while! He must have run out of FPGA space for the update and Mappers. 16MB of Rom space, bigger FPGA, and an I/O controller of sorts.

Not sure to trust this site... But if you are still looking for a Dstwo Plus to play around with (despite its battery drain issues)…

This site still claims to have new ones in stock.
Don't ever trust these assholes, they scammed $73.90 out of my ass, because I fell for their legitimate looking website and stupidly tried to order a DSTWO plus cart.

I guess I'll just have to smack'em with a chargeback from my bank.
