Re: Spectrum Next core on MiSTer fpga?
Assuming this is the correct part, they are for me £53.99 with free UK shipping. https://misterfpga.co.uk/product/mister-sdram-128mb-module/ This not the correct part. Next core needs SRAM memory. That module is only SDRAM. There is no official part for 32MB+2MB module. This is the part: https://gi...

Re: Spectrum Next core on MiSTer fpga?
Just as an impartial person in this discussion, the cheapest price I can find for the DE10 only is £103.97 (UK Pounds). I believe this includes VAT and shipping. This is approximately 113.24 Euros and 133 USD. https://www.mouser.co.uk/ProductDetail/Terasic-Technologies/P0496?qs=%2FacZuiyY%252B4ZdDL...

Re: Spectrum Next core on MiSTer fpga?
As for this thread: -MiSTer costs 130USD. With 32 SDRAM (which is what's needed to run 99% of stuff) and OTG USB its price is ~135 Euro. This is completely false. Put me a link where I can buy for that price. Also for Next core you need another SDRAM+SRAM module that costs 38 EUR+shipping. -I was t...

Re: Spectrum Next core on MiSTer fpga?
ZX DOS+ costs 130E. It's actually more than MiSTer, which is also pretty crazy :) It's also a continuation of ZX Uno, which got abandoned and left in the cold. If the extra (non-Spectrum) cores on ZX DOS+ are the same as the ones on Uno then they're not really up to scratch. He says it can do Next,...

Re: F'n Balls
About the bug, it's solved. That was ULA snow because I register was $FE and in 128K $C000 is switching between 2 pages (one of them is 7 for shadow and is contended). Solved with the help of Ast A Moore who suggest to change the I register to $3B. About the bugs when launching on 48 BASIC on 128K m...

Re: tap8k. simple, small and fast loader
I have released a version that includes shrinkler compressor, developped here . https://github.com/antoniovillena/zx7b/blob/master/shr8k.asm So from a input binary file assembled with org $8000 you will have a compressed TAP file like this: https://github.com/antoniovillena/zx7b/blob/master/demo.tap

That's faster: LD H, 0 LD D, H ; DE = HL LD E,A ADD A,A LD L,A ADD HL, HL ; x04 ADD HL, DE ; x05 ADD HL, HL ; x10 ADD HL, HL ; x20 ADD HL, DE ; x21 ADD HL, HL ; x42 ADD HL, DE ; x43 Well, if your range is up to 77, then this will be 3 T states faster (dividend goes into A): LD H, 0 LD D, H ; DE = HL...

Shrinkler, LZ77+arithmetic coding compressor
The decompression routine is very slow, but it compress better than exomizer. That converts to the perfect compressor for 4K demos. The original code is from here:

Re: tap8k. simple, small and fast loader
puts machine code inside BASIC loader. What assembler do that?Ast A. Moore wrote: ↑Sun Dec 10, 2017 3:18 pm I’m also quite confused. Is it compressing the data or simply puts machine code inside the BASIC loader? Because you can do both with many assemblers already.

Re: tap8k. simple, small and fast loader
Write a simple TAP using Pasmo and let's compare. I am sure with tap8k the loading time (and filesize) is almost half. Pasmo already generates .TAP files, and you can simply concatenate a binary output with a pre-defined basic loader.TAP. What specific case does it solve ? Looking at the code, it se...

tap8k. simple, small and fast loader
I did this tool that can be useful. It generates a .TAP with only the basic block from a binary file (assembled with .org 32768). It's good for small games or tests (because you don't have loading screen). https://github.com/antoniovillena/zx7b/blob/master/tap8k.c https://github.com/antoniovillena/z...
