+Mitch Posted February 5, 2008 Share Posted February 5, 2008 It depends what size game you're doing. Most likely you'll want a 27c010 or 27c020. Mitch Quote Link to comment Share on other sites More sharing options...

The switch switches between the lower and upper half of the ROM as the SMC-branded Realtek RTL8139C chip can flash ROMS only up to 128KB. I use the ctflasher along with a few simple scripts that cut the ROM image in two and burn them in two steps. Many of the Flash ROMs from the ctflasher's list of supported chips can be easily found in old PCs in the form of the BIOS. So you can most probably get the NIC and the Flash ROMS for free and don't have to search for EPROMs and a programmer anymore. Pasiu's cart supports the 2xy020 chips only. The PCBs can sometimes be spotted on eBay, which is where I got mine from. The WL50 suffix in the NIC's model is important, those without it have almost always only a 28pin DIP socket! Some other carts: Sorry for the ugly-looking network card but I had to use the 40pin ZIF socket because it was much cheaper than the 32pin one.

per Posted March 24, 2008 Share Posted March 24, 2008 (edited) What's the difference between the 27C020 EPROM and the 27020 EPROM? (What does that "C" mean? this appears in other chip series too, like the 28x EEPROMS, etc...) *Edit* And BTW, does antbody know the carriage-read cycle time of the Lynx?

The easiest way to cut off the rom image is to use a unix command "tail". You can easily find the command "tail" compiled for Windows also. What you want to do is to cut off the first 64 bytes of the game.lnx file and rename it to game.lyx If the game.lnx is 256k then the command tail --bytes=262144 games.lnx > games.lyx will do the trick. (The command "tail" takes the last 256k of the cart) Another problem is that usually your cart is wired for 256k games. To play a 128k game on it you need to split the lyx image into 512 byte pieces and duplicate each piece and glue them together again so you get the required 256k rom. -- karri <a href="index.php?showuser=10054">jaguar_fan View Member Profile Add as Friend Send Message Find Member's Topics Find Member's Posts ipsmenu.register( "post-member-1490919", '', 'popmenubutton-new', 'popmenubutton-new-out' ); Fri Mar 28, 2008 10:58 AM Post #10 Moonsweeper Posts: 335 Joined: July 17, 2006 From: Germany QUOTE (karri @ Tue Mar 25, 2008 5:40 PM) QUOTE (doctorclu @ Tue Mar 25, 2008 4:33 PM) QUOTE (per @ Mon Mar 24, 2008 3:17 PM) QUOTE (calfranklin @ Mon Mar 24, 2008 9:47 AM) Just wondering if there's a way I could play downloaded game roms on my Lynx and not just on the Handy emulator?

doctorclu Posted May 17, 2008 Author Share Posted May 17, 2008 Hey all, I've been working to get a eprom cart working. Here so far in this picture shows that I got the B&C eprom cart, and added four rows of sockets so I can choose from either 1 meg or 2 meg games. Now the part I didn't realize would be so difficult. Can someone please take the Paperboy image I've attached and transform into the image file it needs to be for a eprom load? I have 27c020 ready to go on this. Afterwards, can you let me know what you did so I can try it. My problem right now is too many factors. I need to burn a rom, figure out where the rom goes on the board and how, and oh yeh, I am not sure my eprom burner will do the job. First time. It would be nice if I had a good image to work with so I can get the eprom burner in line. If someone can help me convert this image, I'd appreciate that. If not Paperboy, then some workable image I can burn. Thanks! Paperboy.zip Quote Link to comment Share on other sites More sharing options...
Nimtene Posted May 17, 2008 Share Posted May 17, 2008 (edited) For your first time, instead of transforming the Paperboy (128K Rom) into the right format for your 27C020 (as Karri describes above), I'd suggest you start with a 256K *.lyx one instead, which will fit without much fuss.

Fadest Posted May 17, 2008 Share Posted May 17, 2008 You can also use the Yastuna 2 ROM, it is freeware and available in Handy *.lnx format and burnable *.lyx format in the same archive. http://fadest.free.fr/Yastuna2/indexen.html Quote Link to comment Share on other sites More sharing options...

Not only do I get a 2 mb image to play with, but the LYNX FINALLY GETS A GAME THAT STARTS WITH THE LETTER "Y". Now we just need to work on "O" and I think "U". In the meantime I will fire up my rom burner to see for starters if my burner will work. Quote Link to comment Share on other sites More sharing options...
Nimtene Posted May 20, 2008 Share Posted May 20, 2008 Thank you! And what did you use to convert this image?I opened the "Handy" headered *.lnx file in Xvi32 Hex Editor,deleted the first 64 bytes of the file, then saved it as *.lyx. You'll definitely want to make a Yastuna 2; Awesome release. Quote Link to comment Share on other sites More sharing options...

Irgendwer Posted May 28, 2008 Share Posted May 28, 2008 Looks interesting. Do you want to tell us more about it? There is not that much to tell about it. It's a Lynx-Eprom-Adapter I've build some years ago. It supports 1m*8 eproms (e.g. M27C801), where you can put up your cart-images. I wrote a little software which can mix up the images to form a 1M image. So you can merge from 8x128k games up to 2x512k games into one burn file. The picture shows a eprom with a combination of 2x128k games together with 3x256k games. The active image can be easily selected by using the up & down buttons of the numeric selector on the left side. That's all...

+karri Posted May 29, 2008 Share Posted May 29, 2008 it's just a coder that replaces jumpers (like those on Karry's card for example) But the wheel is more user friendly for sure. I am also experimenting in a software wheel because there is no way I can remember where I put the image. The software wheel would use a i2c 8 bit latch. But I am still building the mod and need to solder 8 more wires before I can test it. -- Karri Quote Link to comment Share on other sites More sharing options...

Irgendwer Posted May 29, 2008 Share Posted May 29, 2008 Wow, this is interesting. Do you still make this Lynx Eprom Adaptor? The project is about 7 years old and I've done only two adapters - one for a friend & one for me. I could order some pcbs, but since the price depends on the number of units, the single pcb could be a quite expensive part (in a prototype series about 12,- EUR) and the test socket & code switch is also not that cheap. I also have to mention that the adapter is not very comfortable for Lynx I units. My friend has a Lynx I and I designed a kind of 'rated break point' to divide the lower & upper part of the pcb - allowing to connect them by appropriate ports & a ribbon cable - but the cartridge door / handle still has to be opened. How many units could I sell here? CU Irgendwer Quote Link to comment Share on other sites More sharing options...

Atari Smeghead Posted June 3, 2008 Share Posted June 3, 2008 How many units could I sell here? CU Irgendwer I'd be interested in one! How do you load software onto it? I own nearly all the Lynx titles, so I'd want it, primarily, to be able to play demos and unreleased Lynx games. If I could easily find and load that software, I'd certainly buy one.
