Wouldn't it be relatively easy for someone to write an app that allows transfer of game saves to and from the SD card? Not in bulk like the ghetto-ass Tennokoe Bank does it. That's for homeless people. I'm talking a slot-by-slot transfer and backup. I'd love transferring saves around the internet so y'all could see my wicked high scores on your own screen. Unless Krikzz doesn't allow the TED to write to the card?

Supposedly it's possible to read/write the SD card from the PCE side.

Someone was already working on a SD READ/WRITE library for the TEDs, on the PCE side. Well, reading lib part is up and running, not sure about how far they got with the write function. This wasn't a coder from Krikzz crew though.

Saw this:  http://pcedev.blockos.org/viewtopic.php?f=5&t=90
So writing to the SD card works.

At this time, there isn't a way to transfer saves.  You are stuck looking for Tennokoe bank card and an adapter for USA system.

I do hope someone comes up with a program that can transfer saves between SD card and the internal memory (Turbobooster Plus, Tennokoe 2, CD system, and Duo)

Yes, definitely, but it would be even easier to write it to a PC with the TED's USB port, and nobody has done that yet, either.

As far as I can see, both Mooz and MegatronUK are still fighting to get stable FAT/FAT32 access working, although MegatronUK seems to be close, if not yet already there.

The silly thing is that IIRC there's already a stable-and-tested 6502 FAT/FAT32 library available ... but it won't work for them because they're insisting on using HuC instead of something a little more modern and standards-compliant like CC65.

KRIKzz seems to have HuC6280 SD Card functions working ... the TED wouldn't work otherwise, particularly TED v2's new "save" feature.

KRIKzz has said that he's using CC65.

Is there a connection?  :-k

MooZ doesn't use HuC - he's all asm. It's MegatronUK that wanted HuC support. Modifying CA65 code (not CC65) is fairly easy. I added some functionality to PCEAS2 that kinda helped (those stupid +++ and ---- labels).

Huzzah! Multiple sector writes are defeated! The start/dostuff/stop sequence routines were removed. Instead disk_read_sector, disk_write_sector were added.
You can find the code here: sd.asm
I still need to add the C "exports" and send a pull request to John.
..as the asm side was pretty much done, but I have talked with MooZ in quite some time - so maybe not.

Yep, it looks like Mooz's low-level ASM routines for reading-and-writing an SD card sector were completed about a year ago.

MegatronUK slowly continues to battle to get the higher-level FAT/FAT32 routines written on top of that low-level access.

Here are 2 open-source projects with FAT/FAT32 "C" code suitable for small processors, but they require an ANSI "C" compiler, and so won't directly work on HuC.

Does anybody have a Doujindance modded system and use an Everdrive?

Here's one guy ...

I have a doujindance region modded duo-r, purchased early this year, and it works great with v1 Everdrive. Hope that helps.

And there's a guy on KRIKzz's forum that just got a TED v2.1 working on his Duo-R, but he had to rewire the region-mod to take it's power from a different point (the 7805's input, not output). That worked for him because he's powering his Duo-R with a 7.5V PSOne power supply, and not a regular NEC power supply.

I know I have a US turbo duo that is region modded, and works great with my V1. #JustMy2Cents

KRIKzz got in a new supply of Turbo Everdrive v2.4 cards for sale yesterday.

Anyone feeling brave?

My v2.3 warranty-replacement card is still slowly on it's way over from the Ukraine, so I can't comment on how well the new revision of the card works.

I ordered one (v2.4) yesterday. I have a doujindance modded Duo-R, so wish me luck.

Anyone have an idea of how long it usually takes to get the ED once it's ordered?

I know that the v2.2 version would not work in that console.  The old v1.2 that I have did work great though.  Hopefully the redesign of the v2.4 will make it work.

here is a thread discussing it:
http://krikzz.com/forum/index.php?topic=3279.0

worst case you may have to return the v2 and get a v1 (or find someone here who wants to swap carts)

I have the Turbo ED 1.2. I also have the Super ED 2.0 with a DSP1 chip I added myself.

I bring this up because I feel that Krikzz has run himself thin with feature creep by supporting so many different Everdrives. The Turbo ED 2.x had compatibility issues but the bog standard 1.x works great. Likewise with the DSP emulation not working on the Super Everdrives and the necessity of adding BIOS files for the DSP chips.

Just say I'm glad with what I got but if I had bought a Turbo ED and it not worked on my unmodded TurboGrafx system, I would have been upset. I do wonder about future homebrew for TurboGrafx/PC Engine, but aside from Atlantean and a few demos, there's not much yet, and I don't know of any homebrew on the horizon that require the ED v2.x

Turbografx homebrew seems to still be in it's infancy and sadly the majority of homebrews cater to CD-ROM crowd which I cannot afford the add-on or a Duo.  :cry:

 A lot of homebrew, the 8 and 16bit era, seems to be trending towards profit nowafays. As in, the rom isn't released for free. Not all homebrew, obviously, but a good amount. So a flashcard won't help you in that respect.

I've tested a lot of WIP homebrews using flashcarts on my Atari. If it's good, I usually end up buying it when it comes out. Ditto for NES titles. Oftentimes with NES there is a demo ROM with just the first level playable.

Many games are also now being released on custom flash mappers instead of recycled old Nintendo PCBs. This makes piracy difficult because the custom mappers aren't supported on flash carts or popular emulators, which is fine by me. Pirating 20 year old games because they are too rare or expensive is one thing; pirating newly released homebrews is just douchey.

The Santatlantean demo was very fun and the mechanics were great. Since it uses the same engine, it's enough for me to know Atlantean is gold. I messaged the person doing the Atlantean homebrews as to when another batch would come out. I enjoy supporting the community but it appears they are all gone atm.

Sorry if I'm going off topic. Krikzz is adding the RAM into the v2 Everdrives so future advanced homebrews may take advantage of, but more compatibility problems arise. I'll probably buy an adapter eventually to play Japanese games, but as Krikzz said some region mods don't behave nicely with the v2 Everdrives and I'm wondering if the Obey mod is one of them. If the Hucard RAM uses a bidirectional bus, it might cause problems with the region select chip whereas a straight wired adapter would pass the signal both ways. Forgive me but I'm a little ignorant on how the RAM is utilized.
