carlsson Posted December 22, 2021 Share Posted December 22, 2021 Actually in one of the Swedish speaking FB groups I'm part of, a fellow asked yesterday for a provisional interest in a REU replica. I'm sure there are other hardware people around the world reasoning the same way, now that REU may have become a desirable thing to have for use, rather than just a collectable. So far he doesn't know about price point, probably in the $50-100 range. 2 Quote Link to comment Share on other sites More sharing options...
jrhodes Posted December 23, 2021 Author Share Posted December 23, 2021 Sonic has been updated to version 1.1 now. Grab it from CSDb. 1 Quote Link to comment Share on other sites More sharing options...

This is interesting: Quote Added C128 detection and user choice to disable 2MHz acceleration, as it won't work with actual CBM REUs Anyone have technical details on this?

+SpiceWare Posted December 24, 2021 Share Posted December 24, 2021 I watched a long-play on YouTube, it looks very impressive. Wish I had an REU for my 128. The Holiday Update for my car showed up, so I guess I'll just play Sonic there until the REU replica gets figured out 2 1 Quote Link to comment Share on other sites More sharing options...

carlsson Posted January 2, 2022 Share Posted January 2, 2022 Here is some plans of a REU project: https://garrettsworkshop.github.io/GW4302/Docs/index.html 5 Quote Link to comment Share on other sites More sharing options...
Mazzspeed Posted January 5, 2022 Share Posted January 5, 2022 I've been playing this on my C64 using the 1541 UII+ REU as well as 1581 emulation complete with JiffyDOS - It's simply brilliant! Being able to load the .D81 at JiffyDOS speeds directly into the REU is fantastic as it's so much faster. I haven't tried loading the game off the SD2IEC, however a real or emulated 1581 with JiffyDOS is as fast as the SD2IEC anyway and I'm not too sure if the game is SD2IEC compatible. Hat's off to the developers. It's great to see the REU finally being used to it's maximum potential, the scrolling in eight directions is just so smooth. 1 Quote Link to comment Share on other sites More sharing options...

Eight direction scrolling is not some kind of gold standard, it's just barely better than two directions and one direction. 5 Quote Link to comment Share on other sites More sharing options...

I am really surprised that an REU clone was not released already to be honest. The only options currently for people to actually experience these games on real hardware are with either the (now) super rare REU expansion or a 1541 Ultimate II....or emulation of course. I see all of these GeoRAM adapters online readily for sale, but they are not REU compatible. I don't see the point...just to use GEOS? 1 Quote Link to comment Share on other sites More sharing options...

The primary difference between geoRAM and a Commodore REU is DMA -- the former lacks DMA. This made the geoRAM less expensive, but slower, than an REU back in the day. 2 1 Quote Link to comment Share on other sites More sharing options...
eightbit Posted January 12, 2022 Share Posted January 12, 2022 Well I was able to score a 1541 Ultimate II (not plus, the first II model) which has REU support so I will be able to try this soon on real hardware. That is after my C64 board comes back from repair from Ray Carlsen 3 Quote Link to comment Share on other sites More sharing options...
eightbit Posted January 15, 2022 Share Posted January 15, 2022 (edited) Received my repaired C64 from Ray and was able to test this tonight. Works awesomely. This is much smoother than I expected. It's really a showcase game. But, I chose "compatible load"....which took FOREVER. The Ultimate II has an option for saving REU memory. I wonder if I load the entire game into REU and save it if I will be able to fast load back into it in the future. I have to read more on the REU features on this cart. EDIT: Apparently that is exactly how that save feature works. I am going to have to endure loading this again and then saving the REU memory to file. From there it should load in a few seconds the next time I want to play Sonic Edited January 15, 2022 by eightbit 2 Quote Link to comment Share on other sites More sharing options...
eightbit Posted January 15, 2022 Share Posted January 15, 2022 Ohh, and I forgot to add since I had mentioned I needed repair if anyone was curious. My RAM started "disappearing". The old breadbin was reporting 1988 basic bytes free Turns out the MT ram in this unit is trash and Ray removed all of it and replaced it with some magic "modern" RAM. According to him this RAM replacement should outlive both him and me! Now...back to Sonic! 2 Quote Link to comment Share on other sites More sharing options...
eightbit Posted January 20, 2022 Share Posted January 20, 2022 (edited) Well, being kind of new to the REU (using it with the UII, but same as the real thing) I did not realize one thing. You need a way to load the contents of the REU So, I can load the whole game into REU and save that loaded information. But a loader is going to be required in order to load it back from the REU. I only realized that while messing with Nuvie player and other movie player stuff. In those cases you load the .reu file into the REU memory and then launch the accompanying loader to run it. This game needs an REU version (what I mean is a .reu file and loader) ... or just a loader and leave it to the end user to save the game to REU memory after loading the disks like I did. Having that would cut the load time from minutes down to a few seconds. Unless anybody knows of a generic way of running contents written to the REU?

Leonard Smith Posted January 20, 2022 Share Posted January 20, 2022 Pretty impressive, even though it does require the REU Quote Link to comment Share on other sites More sharing options...
eightbit Posted January 23, 2022 Share Posted January 23, 2022 This also works great using the MiST FPGA computer's current C64 core which now has REU functionality. Confirmed that this evening It means it will certainly also run on a MiSTer with the C64 core as well. Quote Link to comment Share on other sites More sharing options...
Zap1982 Posted February 26, 2022 Share Posted February 26, 2022 I would love to try this on my mini but I have never managed to get it to recognise a USB or firmware update or anything. It always says there is nothing plugged in.. Quote Link to comment Share on other sites More sharing options...
