Does the A7800 have enough resources to play Covox samples? You have to transfer a lot of data. Stereo Pokey can work if you want, I suggest you do it according to XM .: POKEY1 $ 0450- $ 045F POKEY2 $ 0460- $ 046F Of course, the audio outputs would be summed up into one channel. A special firmware version would be made for Pokey Max. To test it, I need a demo. Can someone create music that switches between Pokey 1 and Pokey 2 while playing?

The Pokey Max Stereo + Covox works in mono in the A7800. Tomorrow I'll be talking about making a version just for the A7800, we'll see what comes out of it. Below are samples from Millie And Molly. Pokey_Molly1.ogg Pokey Molly 1 PokeyMax_Molly1.ogg Pokey Max Molly 1 Pokey_Molly2.ogg Pokey Molly 2 PokeyMax_Molly2.ogg Pokey Max Molly 2

Pokey Max was heavily tested on the Atari 8bit and everything was positive. But I will be happy to test any music you show me Tomorrow I should receive the NTSC console, so I will tire the prototype further. If you know games with unusual banking, please send files or names. For now, I'm basing on "Trebors_7800_ROM_PROPack_v3_6"

Today I tested a replacement for the POKEY chip called Pokey Max. Works great, I can't hear the difference in sound between the original chip and the replacement. You can compare yourself. Pokey.ogg Original: PokeyMax.ogg Pokey Max:

Unfortunately, I don't have a single item anymore and I don't plan to resume production. At the moment I am focusing on another Atari project. Thank you all for the positive words about AgaCart

Now nowhere, when everything will be finished and tests will come out positive, I'll start a new thread.

Forgive me for answering in groups, but I'm on vacation and I'm only online for a moment: - selecting a game via the display is not problematic, using directories and subdirectories you can organize files. - I designed the cartridge according to my knowledge and skills, I do not want to be dependent on anyone, order him to write a loader and wait forever for the end. - the two wires visible in the photos are only in the prototype, there are only WE and OE signals for RAM - the selected file is rewritten to the SRAM memory of the cartridge, and remains there until overwritten by another file or the cartridge is powered off. Turning off the console's power does not result in memory loss. - the housing will be designed and printed on a 3D printer after the final PCB version is finished. I don't need a hole in the middle, the hooks on the sides are enough. I once did this for Amstrad: Following your suggestions, I remain with the A7800 and do not deal with the A2600.

In response to the questions: - the power supply is connected to the cartridge, and then the console is powered from it. It is he who decides whether to apply power to the console. If it runs on a regular 9V power supply, it will work with Dragonfly too. The advantage of such a solution is that we do not burden the original A7800 stabilizer, the console will draw less power than with the original cartridge. - the POKEY chips must be arranged on your own, the socket will be soldered under it. - Dragonfly works with an SD card, no need to connect to a computer The list of files and directories is shown on the LCD. USB is a tribute to developers, it's easier to test games this way. - about the A2600 games, I was wondering about it. I still have a lot of resources in CPLD, I could run basic A2600 banking. It should take me about two weeks. I can do it later, but updating the cartridge would require you to have the Altera USB-Blaster programmer.

That's right, there is no menu, you select the file on the display and confirm. The game will load and will allow you to turn on the console. When you change the game, the console will turn itself off, load the new file and allow you to turn on the console. I won't say prices because I don't know, I haven't counted the costs yet, a few things will change yet. The cartridge will not support HSC.

Hi, I wanted to present to you my version of the Atari 7800 SD cartridge. What you can see in the photos is a prototype version on which I learn how to use. The cartridge will be operated using four buttons and the display, of course, it will be in the housing. For correct configuration, the cartridge uses .a78 files and the header. As of today, it supports 4k, 8k, 16k, 32k, 48k files - without banking, 64k, 128k, 256k, 512k with banking. In addition, 16k RAM for $ 4000 and POKEY for $ 4000 and $ 0450. Various combinations are possible. Also supports Absolute and Activision. Below is some evidence that I am writing the truth: Demo Multi-Lock On, 512k + Pokey $4000 Demo 1E78, 128k + RAM Double Dragon, 128k, Activision F18-Hornet, 128k, Absolute E.X.O, 256k + RAM Donkey Kong XM, 144k + POKEY $0450 Bentley Bear's Crystal Quest, 144k + POKEY $4000 or $0450 Rescue on Fractalus, 32k + RAM. Can you confirm that the graphics are displayed correctly? The lower bands are due to the fact that the game is NTSC and I run it in PAL. Ultimately, the cartridge will also have a USB connector that will allow you to load files directly from a computer. I've already tested it and it worked. I'll be back from vacation in two weeks, I'll spend a few more days testing with different files and designing the final version. If you have any suggestions or ideas, please write. And there is also a sticker on the cartridge, designed by a colleague of MotionRide:

Unfortunately, the cartridges are no longer produced.

I have two pieces waiting to be shipped to Australia which unfortunately still is not possible. If someone quits, then I will let you know in this post.

Today I have finished the production of AgaCarts, they will no longer be available. People who have paid and are waiting for shipping (power, ssmac, dougal22) of course have their cartridges guaranteed. People who have confirmed their desire to buy (kevates, vitinillo) also have reserved cartridges. If it turns out that I will have some redundant art, I will let you know.

I have updated the list, the cartridges will be available in a few days, I will send a private message.

@RadiATIon, Have you tried turning off the console and turning it back on immediately? If so, do it several times, the update should succeed. If not, the 2GB card should work. As for the rest of the question, try to move the cartridge to the left or right, as it looks at the wrong connection in the socket.

Record the file with version v5 as the only one on this card and insert into AgaCart, if "P" appears for a moment and then "EE", the update was successful. It's best to check if you have the v5 version by increasing the number of games on the SD card to over two hundred, if it sees them it's OK.

Everything is in the instruction manual included on the SD card and in the first post

This is very strange behavior, first set option two to "0" and option three to "2" and see if anything has changed. If not, go back to version v3 from the attachment and write if it has improved. agacart_v3.zip

Unfortunately, this is not possible.

I added you to the list. Shipments to the US and UK returned. In the near future, please wait for messages from me.

I updated the list. Shipping is possible to countries marked in green with the description "list priorytetowy" (priority letter).

It won't speed up writing at all, it can even slow down. In the loop in which the writing is taking place, I would have to add a button handling procedure, which will take several Atmegi cycles. Write is done byte-by-byte, so with a 256kB file the loop is done 32768 times!

It starts programming when "P" appears. The waiting time from pressing the button to starting programming is 1.5s, in earlier versions it was 2.5s

No, you must delete the file from the card yourself after successfully updating.
