Close enough. There is another lot of 10 for 7.30
By the way, who gonna make cables?


I guess If I had a good schematic, I might be able to make them.
I am okay with a soldering iron.

So are we going back to my idea of just doing a direct of flash instead of using the system link?

Just thought about socket-in-the-cart - possible to mount transistor based RS-232->TTL convertor into cart, right on the socket pins and round hole is much easy and fast to make to compare with square/rectangle one. Standart stereo jack/socket will do the job - TX/RX/GND, but 3 extra chips('138 - decodersomething for decoder, '175('174) - transmitter, '257 or whatever with tri-stable output )

why not using a dedicated RS-232->TTL logical level converter IC?  only 1 extra chip with a couple of capacitors.
e.g. max232

I recommended that a long time ago but nothing came of it and since its 80sFREAK's idea I am waiting on him to form the topic.

2 famifan so how many extra chips in total?

i'm not sure if i completely guess your idea, but only 1 extra chip requires + 5 capacitors.

there is the converter IC that has capacitors built-in (sorry, i dunno the part numbers exactly) and i don't know how much it will cost. Maybe 1 chip + 5 caps will cost less then it.

When you say not cost-effective, what kind of price are we talking?  I know flashcarts are expensive, but there's good demand.

Anyway, i have to track some 5v flash memory in DIP or SOIC->DIP adaptors and some other stuff.

ehm...
also, you can use 3.3V low voltage flash chip in TSOP with low drop output 3.3V voltage regulator.  ::)

Time to vote for shell color. black, red, white, blue, green(teal), yellow, silver, gold.


Go for the gold.

No!   White, WHITE!    Gold will be cheap plastic gold, famicom white is easier to get exactly right than finding the exact red necessary. :redcart:

:help: WHITE!    :bub:

well what's the biggest size of a NES rom we've ever seen
taken from nesdev

QuoteWhat is the biggest NES game ever made?
The largest single NES game that I know of is Dragonquest 4 / Dragon Warrior 4. It has 1 megabyte of program ROM. Also, the Japanese game Metal Slader Glory has 512K of PRG and 512K of CHR ROM, making it also a full megabyte. Several pirate/unlicenced Famicom games are also pretty large.
