Re: Rainbow : a WiFi cart / mapper for the NES !

So let me see if I got this straight. If I set up a local server , and it can have a local ip address, and have a file on the server then the Wi-Fi cartridge can be instructed to access this server and this file? Exactly! You can then use the SET_SERVER_PROTOCOL command to set the protocol (WebSock...

Re: Rainbow : a WiFi cart / mapper for the NES !

i'm super hyped for this and would love to develop something on it. i am wondering how does it handle connecting to wifi. how does it know the SSID and password? The WiFi chip on board (the ESP) also acts as a WiFi access point. You connect to it and access to a web page that allows you to set up y...

Re: Rainbow : a WiFi cart / mapper for the NES !

I use 2 level shifters.
One 16 bit from the NES to the CPLD (74LVC16245) and one bidir 8 bit NES <=>CPLD (74LVC245).
No issue with them as of now!

Re: Rainbow : a WiFi cart / mapper for the NES !

2020-07 update Time to update this topic since a lot of stuff happened since last time. Prototype I'm now using a new prototype with a bigger CPLD and have created a brand new mapper (named Rainbow mapper) to be used with it. Here's a pic of the board: http://www.brokestudio.fr/nesdev/pcb-v1.1-nesd...

Could something like Broke Studios' wifi adapter be used to store the data server side?
Sure, you could save directly on the wifi chip flash memory or on a remote server.

However, for this kind of game, additional wram would help a lot.

Re: Mesen - NES Emulator

Gilbert, I considered that, but I noticed a trend - once someone gets a large chunk of cash from kickstarter, they disappear from forums for a while. Maybe that's because they work hard and are really focus on other projects. I know I'm not really active here, but I still check what's going on once...

Re: Rainbow : a WiFi cart / mapper for the NES !

You mean if the NES floods the ESP ? Communication ESP => NES is not an issue. But NES => ESP can be tricky indeed. For now I didn't have any issue with it, but I should make a test rom that really floods the ESP with various commands, some easy to process (log some debug data) and some more complex...

Re: Rainbow : a WiFi cart / mapper for the NES !

Bandwidth between the NES and the ESP is:

- 4 cycles when writing a byte

Code: Select all

sta|x|y $5000
- 6 cycles when reading a byte:

Code: Select all

lda|x|y $5000
nop
NOTE: nop may be removed in the future

Re: Rainbow : a WiFi cart / mapper for the NES !

Everything is powered by the console and work fine (I have to do some measurements one day or another though...). Didn't measure the bandwidth yet, because that wasn't my priority, but we will arrange that. Or you can clone this repository and build it yourself: https://github.com/sgadrat/fceux (bra...

I kept on working on this project with RogerBidon, me on the hardware/firmware side, and him on the emulator side. We made a lot of progress, and I'm really proud to share with you the first examp...

Re: GTROM/Cheapocabra mapper for Everdrive N8

What ROM version did you use ?
Did you dump the game yourself ?

Re: GTROM/Cheapocabra mapper for PowerPak

What is the difference between "gtrom-ram-test.nes" provided by NovaSquirrel and "gtrom-flash-ram-test.nes" provided by Memblers ?
The first seems to work fine with my Everdrive mapper, but not the 2nd one.
