I have made some tests using bustest and my A4000 and both of my Replay boards (Rev.A with daughterboard and standard Rev.B). What do you think?

Damn!

@yaqube

impressive values! I would love that the 060 board included some kind of SATA port but USB2 will be better than nothing :-)

Woohoo! I can easily attain triple speed AGA blitting on a Replay+Daughtercard!

I noticed you listed VGA mode times. Is that the way to get flickerfree AGA gfx on a replay? To use DoublePAL, DoubleNTSC or VGA modes?

Luckily my gamecode already supports both PAL and DoublePAL even though DoublePAL is mostly useless on a real A1200.

Hahaha! Nice to see I'm not the only who loves AmigaDOS (not WB) around here
I always wondered why the Los Gatos team decided to include connectives in commands like "from", "to", etc... it makes AmigaDOS a very fun yet easy DOS to use. My favorite over Linux and Risc OS.

Yes, all programmable modes like DoublePal, DoubleNTSC, Multiscan etc are supported.

I meant is that the only way to get a flickerfree interlaced AGA display?

Like does Replay have a hardware flickerfixer built-in that can deinterlace the Amiga's interlace modes? And if so, is it free? Or does it use the same amount of bandwidth as the corresponding Double#? mode?

My real Amiga has a hardware flickerfixer so all my PAL and NTSC interlace software displays to my VGA monitor without costing me any extra bandwidth.

I'm just trying to figure out what to tell ppl when they play my games on Replay.

My conclusion:
* Video modes that use more bit/s will leave less capacity for other stuff.
* Faster memory interface = more capacity
* Separate memory for CPU = faster read/writes

The RP+060 is perfect in all those aspects.

[Heiroglyph]

Considering it's almost finished and not yet optimized, those numbers are incredible.

Congrats guys, that's so much better than existing motherboards that you're really making me want one.

[cunnpole]

Will using the expansion board without the 060 give any performance boost over the vanilla Replay? Or would I be best to get my hands on the cheapest RC model I can find?

I don't have any plans to implement a flicker-fixer. Productivity and DoublePAL/NTSC modes are much faster on Replay than on any AGA Amiga (over 8 times) so it's not a problem. Besides you have a bunch of nice RTG screen modes so why not use them?

It would have been the MetaComCo guys who included those commands from TripOS, not the Amiga guys

What about when you want to fire up a game and it runs in non double PAL and you're wired up to a monitor that can't take 15kHz?

Nevertheless I'm sure someone will come up with a solution. WHDLoad+Mode Promotion?

Do you have a particular game in mind? Remember, you have a scan doubler, just not a flicker fixer.

Off the top of my head, the only games I remember playing that made use of a flicker fixer were Sim Ant and SimCity2000. I think Sim City could use other screen modes, not sure about Sim Ant.

Hello,

While a fan of the current board form factor... would you also consider a different layout of the board that contains the current FPGA Arcade and the '060 board? I for one could definitely live with a larger board. My thinking is either an ATX size board - or a board that we could fit inside of an existing Amiga case - like an A1200 or A4000.

Thanks!
