News - Hippiman changed his residence, then started to make a game, John Silver bought studio speakers, first ATM 8.00 board was finally
News by Alone Coder Changes in NedoLang system: - It now supportsdirectories. Instead of some 200 files in one directory, each of the projects now has a separate directory, and there is a common../_sdk/ directory. Slashes like / are used in parameters. - Severalbugfixes: in compiler, libs, nedotrd, and nedores (thanks toHippiman ). -Source file is shown in compiler error messages (in assembler errors, there are still problems because of lack of memory). - New functions inio.h: fread(PBYTE buf, UINT size, UINT n, PBYTE file); loadfile(PCHAR filename, PBYTE addr); findlastslash(PCHAR s) (skip path); readsectors/writesectors(PBYTE buf, UINT trsec, BYTE count). There was alsocomparedesc(PCHAR filename, PBYTE desc) (compare TR-DOS descriptor against the filename) but commented because of extra size. - Nativebatch processor that runs executables with given parameters. I corrected the batch files so that they can run on both Windows and Speccy. Batch processor resides in OxfaOO and gives away parameter strings pointed by CH_ADD=23645. So I don't need sophisticated basic loaders for testing any more. - Sound FX libraryayfxplay.h from Ball Quest and Evo SDK was integrated. -128K runtime library added:runtime.h. Provides ports Oxfe, 0x7ffd, various interrupt setters, and interrupt handler (with separate stack and top of stack restore with DE, two user callbacks - one before the music, another after it). - New libraryprint.h. It includes setxy, prchar, nprintf (a kind of printf supporting %s, %c, %d, %x, %%). It types on screen (only the upper third is free for utilities now because there are up to 8 open files). - Newnative utilities: diff (compare two files and show differences on screen), nedodel (delete a file), movedisk (remove deleted files from TRD), and non-native (yet) utility nedopad (cut or pad a file to a given size). - So the testing of NedoLang is automatic now! Each of the parts (compiler, tokenizer, assembler) fits in one TRD and doesn't require a RAM-disk. Then I made two versions of str:str.i vs. str.c (for ARM Thumb compatibility), and two versions of io:iofast.i vs. io.i + io.c (to make possible to use a TRD RAM-disk for ARM Thumb target). ARM Thumb target was added in compiler, tokenizer, and assembler. Compiler for ARM Thumb already works! Initially I tested it through Keil assembler and Phyton debugger ( Phyton assembler is incompatible) - Z80 tokenizer compiled for ARM Thumb produces right result on RAM-disk. Then I made tokenizer and assembler process the same assembly source and generate the same output as Keil assembler. Function addressing bias on Thumb was a pain: pointers to functions must be odd, and pointers to data must be even! Finally I dropped Keil assembler compatibility to make everything easier. Some of ARM Thumb commands are not used in the compiler, so I can't test them. Any help? Download the release candidate from http://alonecoder.nedopc.com/zx/ Only native IDE is missing yet. By the way, have anyone seen the sources of C Warp? * * * Hippiman changed his residence, then started to make a game engine atop of NedoLang. Time came to publish his article about linking modules in NedoLang's competitor Evo SDK :) NedoLang has EXPORT feature for this. Louisa draws a 3D model of our future home. We recently measured the flat. John Silver bought studio speakers. They reproduce every click in music :) I was shocked to see how noisy were original Beatles recordings and many more... Savelij13 with the help ofDimkaM finished a new version of TR-DOS for ZX Evo that allows running sophisticated loaders. TDD/MSD from Ufa reappeared after many years and produced an unofficial fix in ZX Evo powering schematics. His groupeeSAVC wrote a couple of open-source Speccy utilities: view_keys and font-convert-ed (see them here - long time no supplement in the newspaper :)), but soon vanished. As I guess, the first ATM 8.00 board was finally assembled by Zorel and will be sent toMaksagor. This is the first incarnation of ATMЗ on small-scale integration chips. I forgot to mention something in the previous issue. Hungarian hackers portedWolfenstein 2004 to Enterprise 128 - very close conversion. Even the music was converted. They made that for some Enterprise compo but haven't contacted me in any way >:( A number of demoparties happened, so it would be interesting to read some sceners' thoughts about demoparties from old logs (see the next article).
