That ship has already sailed...300 quid now.

2 GB is fine for ZX Baremulator.

Batty looks great! Just enough colour to lift the sprites/score off of the background.

I spotted this on twitter :

I thought it was interesting so I am passing it on. Three PCB manufacturers are in the thread, offering their services. I guess these PCB companies run bots searching for words like 'prototype' to find customers.

I have been looking at the ROM disassembly and noticed the routines reference system variables using the IY register. IY is set to 23610 and system vars are read using an offset to IY. This is useful for loading a system variable into registers other than A, as LD r,(IY+N) can be used on all the reg...

Here are some pics below. Always love seeing projects like this. The recreated works great with zx baremulator and I agree it is best used with the pi externally to save chopping the case. I have my Pi attached on the back of the monitor on a harness, so you cannot see it. Your case will look ace.

Update.... Progress has slowed due to work and other distractions but some advances have been made. I have written my own text scrolling routine which is a vast improvement on the scroll used by the spectraNet ROM. I will post the scroll code below. I am very open to suggestions for this routine. T...

On each issue of each magazine you find has a screenshot, the fake name and the real name of each game Great site! I enjoy browsing tape magazines. I have found one error. On the page for 'HIT GAMES' there is a snooker game 'Biliardo' with no original game quoted, it is a rip of Steve Davis Snooker...

oops...i did not see Morkin's score

This game is good!

I have beaten your score...

For this reason, I suggest you move this project to Github and post a link here, instead of posting copies of your code directly. I will look into this. I am not a trained programmer so I am never confident my code is acceptable. I strive to get a piece of code to work, and gain satisfaction when i...

I do plan on writing a socket library for the Next. This is awesome news. I took a brief look at the AT codes for the ESP , and they were fairly complicated. A socket library would be great, it would making converting spectranet code over to NEXT pretty simple. Coding such a library seems, at first...

Another update on progress. Big breakthroughs with client-server communications. I have coded a keyboard entry routine. I have coded a main client loop which polls the socket for incoming data, prints data when it arrives, reads keyboard into a buffer and sends the buffer when enter is hit. So basi...

I had not heard of this game until today (I never used a TI). Looks like a good game to port over. Will the Spectrum version have the speech from the original?

Recently I have been exploring the fabulous SpectraNet add-on. The socket library for this device is excellent and mirrors the standard socket library used in python, C++ and most other languages. The documentation for use in z80/Spectrum assembly is first rate. My NEXT related question is, how is s...

I have pretty much given up getting ZXDS to run from the SD card on a DSi. I now realise that getting unofficial software to run on the DSi is a clandestine occupation that is best left to software thieves and 1337 hacksters. The irony is, I was given the DSi by my son (who upgraded to a switch) and...

I have spent this evening trying to get [mention]Patrik Rak[/mention] 's ZXDS to run on a DSi with no success. I am using the Memory Pit exploit (camera/SD card) to launch a homebrew menu. When I launch ZXDS I get a splash screen with 'ZXDS IS BOOTING PLEASE WAIT...' but nothing happens. I have left...

[mention]777[/mention] The not_zero in my example was just an example label you don't need to add that to your code. If I am honest, I found your code hard to read so I am just explaining opcodes as best as I can. My examples were not solutions for your code starfield problem

To be fair, it would be good to read some books explaining the basics. I could confuse you more with my lack of proofreading posts before hitting submit

I edited the above post from equals to not equal

jp nz jumps when the zero flag is not set. The zero flag gets set in a number of ways. An example would be cp 7 , cp performs a subtract on the accumulator but does not change it, if the result is zero the zero flag gets set. So : cp 7 jp nz, not_zero the jump will only happen if the accumulator do...

ok, so what does it do? The AND operand performs logic on the bits of the accumulator and the given number. AND logic is as such: 1 AND 1 = 1 1 AND 0 = 0 0 AND 1 = 0 0 AND 0 = 0 an example : accumulator = 7 (binary 00000111) AND 14 would set the accumulator to 6 7 = 00000111 14 = 00001110 6 = 00000...

Wow, I had not heard of this release. It was released in may 1983, the same year Chris Sievey released Camouflage with a ZX81 video.
