Maybe time to consider another filesystem than FAT32 ?

UFS perhaps? ;)

Regarding the memory controller on FPGA Replay. Maybe a solution is to have the logic-core to measure and adapt the timing to the memory on-the-fly ..?, or at least som kind of dynamic update.

What are the most up-to-date forums for FPGA Replay currently?
(amiga.org seems pretty inactive)

Has the source been released to anyone?, it was supposed to be an open source project. But that doesn't seem to materialize fully.

Partnerships has their own pitfalls. Being just one person that makes the decisions certainly makes that process easier, albeit perhaps slower.

Keeping sources available is a matter of ensuring that the project doesn't die out from one person and that many people can contribute.

I don't think Mike J will bury his project like Thomas Hirsch did with his private Natami boards/forums.


Is NatAmi dead-dead?

So what is the status of the Natami project in short?

Now if AROS 68k would work with E-UAE ..

I think this is the best possible solution.


As long as you don't need to replace the core every 2 minutes..
(due to writing a new one)

Sneakernet vs wired net..

Sam trick possible for the ARM CPU simultainously? (ie without altering physical wires)

Does AROS 68k run on FPGA Replay currently?

Btw,..  how much of the FPGA "space" is used currently?

So "currently" it uses 60% if the space including the softcore.  I guess the space uses by the softcore could be recoved if using the daughterboard with a real 68060.

i think the point with FPGA is to have it all in HDL-code such that one can tweak characteristics at will and share.

Different from SDIO I presume?

Toshiba FlashAir only mentions being able to read from the card when inserted in a digital camera. Same with EyeFi but Flucard seems to support some P2P receive mode. The control is done with manipulation of "picture files", definitly an ad-hoc hack.

Sega megadrive#Technical specifications
 * CPU: 68000 @ 7.61 MHz + Z80 @ 3.58 MHz
 * RAM: 138 kB total
 * Video: Yamaha YM7101 (seems pale compared even to a VIC-II)
 * Sound: YM2612 5-channel FM and 1-channel FM/PCM, SN76489 4-channel Programmable Sound Generator
 * Cartridge via serialized interface.

Yeah it seems doable. If someone actually get inclined enough to do it is another matter.
