ED64 v3 in progress

[KRIKzz]

ED64 v3 is hi-end solution for N64. ED64 v3 will be significantly more expensive solution than v2x, but i will not stop sell and support v2.
v3 uses top quality components, improved architecture, which allow to make more accurate flashram implementation. New cart have separate battery memory for saves, so, not need to reset system to backup save memory! Also, separate RAM allow to release last 64KB of ROM memory (v2 uses last 64Kb of ROM memory for saves, if game use SRAM or FLASHRAM saves). May be some other features will be implemented, they under question at this moment

is there a cic clone on the lower left? ^^

It is real CIC chip

Good to know!

Tasty! I have a v2 which I am very happy with, doesn't look like enough of a difference for me to consider swapping less of a drastic change from v1 to v2

Actually, pretty hard to make much better than v2 in terms of hardware, cuz v2 already have all what really needed. Saves without reset, probably the most important improvement of v3

Sounds awsome Krikzz. Keep up the good work! Btw, what would be able to use the extra 64kb of rom memory? Potential homebrew?

Will RTC be implemented?

I have plans to implement rtc in v3

Thats kick ass! IIRC Doubutsu no Mori (Animal Forest) was the only real game to use it, but at least this will push up the compatibility up to 99.99% (Damn Banjo Tooie PAL )

It is not extra 64Kb, it means that actual max rom size for v2 is 64Mbyte minus 32Kb (if sram used), or 64Mbyte minus 128Kbyte (if flashram used). Whole 64Mbyte avaialble only for games with used eeprom or wihich have no save meory at all. V3 can use whole 64Mbyte of ROM memory with any type of saves

if V3 has RTC i will for sure purchase it.

This is really intriguing.  I've yet to purchase an ED 64 and am looking to in the near future, so I'm definitely interested to see what features are added to improve on V2. From what I've read on this forum,  the V2 ED 64 seems amongst the best of Krikzz's flash carts, so what are some potential "upgrades" to this version to merit the "significantly more expensive price point"? From what it sounds like, it's a much higher quality build, so I assume that means greater reliability/longevity? The implementation of RTC sounds cool, I'd love to try the original Animal Crossing game. What exactly does "more accurate flashram implementation" translate to the end-user, Krikzz? What features are under consideration for you to add, and what are some features that the community would like to request?

Good job!

Don't expect to some huge advantages over v2.  As i already said, v3 can save without reset and it is the main difference. May be v3 will have rtc, may be hardware NES emulation in fpga, i can't say for sure at this moment. From rational point of view, v2 probably will beat v3, but if you want ultimate solution, and not mind to overpay a bit, then v3 is your choice.

I got a lot of engineering skill in last few years, i used all this knowledges during v3 projecting. From physics point of view v3 is more accurate, but it not means that cart will work more years, or something like that. There is nothing realy notable for users.

Pretty hard to explain, but i will try. N64 should have access to ROM during the transfer of memory block inside of flashram(bloc writting), but v2 does not have separate RAM chip with separate bus, so, i used tricks with bus monitoring to avoid colisions. Bit ugly, but trick works. One more thing which is not notable for user (:
