Rilasciata la nuova versione delle DiagROM v1.0

Cosa sono le DiagROM?

Le DiagROM sono delle ROM diagnostiche per gli Home Computer della serie Commodore Amiga. Queste ROM tornano molto utili in alcune sistuazioni, tipo quando il computer non esegue correttamente il boot o si blocca.

Changelog:

  • RTC Test improved with OKI Chipset support (but RTC test still is kind of buggy)
  • Remade the autoconfig handling for much better ZorroIII support etc.
  • Possability to turn on/off cache in manual memortedit (this WILL crach your machine on 68000/68010)
  • Added an experimental “no chipmem” screen to try to figure out biterrors with rasterbars. (dark bar=dead bit, light bar=working bit)
  • Added support for Amiga 1000 with a limited version of DiagROM.
  • Parallel and serialporttests using SysTest compatible loopback adapters.
  • Diskdrivetests.
  • And.. some internal changes and stuff I actually forgotten.

Updatehistory:

  • 2017-10-01:
    • Long time since last time:
    • Added tests for Parallel and serialporttesting using SysTest compatible loopbackadapters
  • 2017-07-30:
    • Added possability to run on A1000 as bootstraprom. I have removed moduletesting and gfx test-screemn to save space.
    • Some additional bugfixes.
  • 2017-07-06:
    • Fixed a bug, when setting DTR high I accidentally put Dikdrive motor on!
    • when no chipmem is foundand no fastmem, instead of just flashing a green screen, it now checks memaddr $400 and shows in stripes biterrors. bright color=bit working, dark=bit error. evbery 15 frame it flashes and steps +4 bytes of memaddr to check
  • 2017-06-17:
    • Oh! yes long time. Now DiagROM is opensource avaible at https://github.com/ChuckyGang/DiagROM
    • Totally rewritten Autoconfig, now handles Z2 and Z3 and should be working. if you get stuck in a loop (autoconfig not working) it
    • will halt after 32 “boards”. Also in ManualEdit mode, I have inlcuded a function to turn on/off cache. to debug cacheissues on CPU Cards.
    • BE CAREFUL! this WILL crash if you run it on a 68000/010
    • Also fixed bug of garbage in menus.

Dragon32-Coco2 Multi-Cartridge with Extensions (VideoPac-Vectrex)

La Multi-cart di Rolo è stata progettata per supportare i computers della serie Dragon 32-64/CoCo 2 con le ROM su cartuccia e che vengono eseguiti dall’eprom all’indirizzo da $c000 a $ff00.

La cartuccia può contenere fino a 64 8k-rom con una dimensione delle rom che puo’ variare da 1k a 16k. È possibile scegliere uno slot di memoria da 00 a 63 anche a Computer accesso e poi premere il tasto RESET e il programma verrà avviato.

Tutto ciò vi consentirà di utilizzare in modo semplice il Dragon 32-64/CoCo 2 senza hardware aggiuntivo: nessun cavo, nessun drive, nessun alimentatore aggiuntivo.

La Multi-cart Dragon 32-64/CoCo 2 ora può essere anche utilizzata con altri sistemi.

Attualmente ci sono tre adattatori disponibili:

  • VECTREX.
  • Odyssey 2/ PHILIPS G7000/G7200/G7400.
  • INTERTON ELECTRONIC VC 4000.

Una compilation di Rom (files) per tutti e quattro i sistemi può essere inserita su un’unica eprom (27C4001), aggiungendo versatilità al dispositivo.

Rilasciata la nuova versione delle DiagROM v0.9

Cosa sono le DiagROM?

Le DiagROM sono delle ROM diagnostiche per gli Home Computer della serie Commodore Amiga. Queste ROM tornano molto utili in alcune sistuazioni, tipo quando il computer non esegue correttamente il boot o si blocca.

Changelog:

  • A lot of internal changes.
  • But changed keyboardhandling in “Manual Edit” mode, hopefully keyboard works better now.
  • Chipmemdetect at startup does more tests to capture more biterrors.
  • Also added tests if CPU can do odd/eveb reads and writes. Request by Terriblefire.
  • Added a testpicture as GFX Test
  • Added test for RTC Chip, reads both types you have to know what chip is in your machine.
  • Added a experimental Autoconfig support for Zorro II boards and memory, Remember that you can only run this ONCE.
  • Autoconfigcode is based on Terriblefires code with addons by me.
  • Audiotest now includes several notes and waveforms and also a module.

Updatehistory:

  • 2017-04-15: Added Support for OKI Chipset in RTC Test
    • Added (somewhat experimental) support for Autoconfig for Z2 boards.
    • Must say thanx to Terriblefire for autoconfig code. (with some changes by my)
    • Added test at startup to see if CPU can do odd/even byte read and writes
    • Bumped version to V0.9 – Next Stable release
    • Released while being at the Revision demoparty.
  • 2017-02-25: Moved mainmenu alternatives to make space for more maintest-menus. also added some for future use.
    • Started on Others tests/RTC Test for the moment only showing ricoh RTC chip (A4k etc)
    • Removed temprary debugfunction added the 18:th.
  • 2017-02-18: Minor changes. sometimes when exiting a testscreen you got to the mainmanu instead of the submenu. cleaned up now.
    • also added a fakefastmem allocation at the boot so you can run stuff in fakefast by pressing LBM at poweron if needed.
    • TEMPORARY DEBUGFUNCTION: while dumping serialport at beginnning, screen also flickers while doing a serial timeout.
    • this is to figure out if machine still runs to veryfy I can do serialstuff (and detect failures) if paula is missing.
    • will be removed soon as it screws up onscreen colorcodes.
  • 2017-02-15: Added a testpicture, testscreen is moved in menu and will still bug. this will be reworked soon.
  • 2017-02-04: Simple audiotest is now improved, it now plays different waveforms, I have checked the frequencys with my Rigol scope.
    • But 20.6Hz in my headphones sounds weird, maybe should remove it in the test. the only thing not working there now is setting volume.
  • 2017-01-30: In Manual edit: added when using “goto memoryaddress” when pressing x it clears the string totally. Also hopefully fixed keyboardbug making
    • it more or less impossible to use keyboard on some machines.
    • Fixed bug showing strange flickering spritebugs random
    • Changed that in initial chipmemdetecting it checks more combinations of bits, this will make detect slower (due to serial output) but will detect more
    • biterrors.
    • TEMPORARY function: pressing fire/mousebutton in joystickport while poweron will totally disable serialoutput. this is to be able to run with broken
    • Paula. Will look into a better solution. so function will maybe be removed.
    • Added a testmodule, A groupmember will make a chipmodule for me later to have here. Now using the classic “Echoing”
  • 2017-01-06: Long time since last update. Hollidays etc. Anyway some minor internal fixes and a basic low-res testscreen added.

Rilasciata la nuova versione delle DiagROM v0.8

Cosa sono le DiagROM?

Le DiagROM sono delle ROM diagnostiche per gli Home Computer della serie Commodore Amiga. Queste ROM tornano molto utili in alcune sistuazioni, tipo quando il computer non esegue correttamente il boot o si blocca.

Updatehistory:

  • 2016-10-22: Fixed bugs in new Chipmemdetection that made it not detect any chipmem if there was missing/Broken chipmem in the beginning. Added errorhandling in the startprocess, so it can show on serialport if there was a exceptionerror. also will show colorcodes on screen. done some smaller bigfixes. Will bump versionnumber and this will be the stable version. It will take a while until next stable version is bumped. Need to do floppy, serial, paralell tests etc before that will happen. but you always have the daily version.
  • 2016-10-12: New Chipmem detection now handles shadowram so it should stop detecting memory instead of giving false 2MB Chip. IF no Chipmem avaible and machine can detect fastmem (NON autoconfig. more or less only A3000/4000 motherboardmem) it will now start using fastmem only. (screen flickers in different colors instead of printing text, nullmodem only) Fixed addresserrorbugs at CIA and joystickport tests on machines with 68000CPU. also should have correct CIA timing on slow machines. IF fastmemshadowram is detected during memorytests, test will exit. MANUAL test have a option to disable that test.
  • 2016-10-07: LONG time no updates. Familystuff. Anyway. decided to do a total redo of initcode especially chipmemdetection. Detection is slower, but progress is printed on serialport so you can see address checked and if failure (in the beginning of the detection) you will see what it wrote and what is read to help debugging of chipmemproblems. Screen should flicker in green while detecting. drawback is that some tests (cia and joyport tests) now generates an addresserror. Will have a look of that.

Assemblaggio e Sostituzione del vecchio DualSID con il MixSID

Assembly and Replacement of the old DualSID with the MixSID

Assemblaggio e Sostituzione del vecchio DualSID con il MixSID.

A differenza del DualSID ho dovuto sostituire i due condensatori elettrolitici (vedi foto) perche’ il PCB del MixSID e’ molto piu’ largo e i due condensatori impedivano la corretta installazione del PCB nello zoccolo del SID.

Rilasciato il nuovo fimware v0.1.7d per la Cartridge SD2Snes

Ikari ha rilasciato il nuovo firmware per la SD2Snes la Flash Cartridge per Super Nintendo/Famicom. Le istruzioni per l’aggiornamento le potete trovare qui.

Changelog:

  • Reworked the in-game hook code again, squeezing out a couple more CPU cycles – compatibility improved further
  • BS-X: new bsx page file by LuigiBlood!
    • contains a proper channel map, notably fixes Fuurai no Shiren: Surara o
    • sukue and most likely more games
    • enables a great number of town features
  • BS-X: better detection for script-type ROMs (e.g. various magazines)
  • Cx4 SKIP instruction timing sped up a bit. Core felt a bit too slow. (this is a makeshift “fix” until I implement the proper Cx4 instruction timing I recently figured out)
  • Fixes:
    • fixed occasional black screen after soft reset (L+R+Select+Start)
    • in-game hook memory area visibility quirks fixed in various situations, notably fixes BS Kirby no Omochabako: Pinball
    • BS-X: fix PSRAM corruption on SNES WRAM writes, fixes a number of games, notably BS Kirby no Omochabako: Pinball (tough one)
    • PPU2 H/V count odd/even read flag is reset on ROM load, this fixes games that depend on it when run after games that leave it in a dirty state – notably audio glitches and freezes in Super Punch-Out when run after Fuurai no Shiren.
    • SPC Player: Fixed a long-standing transfer corruption bug that occurred because the original bulk transfer routine didn’t account for CPU stalls by HDMA (which is abundant in the sd2snes menu). This fixes occasionally missing instruments, corrupted samples etc.
    • fixed an occasional deadlock on bootup where the menu would hang at the “Loading…” screen.
    • fixed hard freeze when selecting a file immediately after disabling the “Hide file extensions” option
    • fixed persistent hard freeze in recent games list handling when running games with long path names (> ~120 characters)
    • revert DAC I2S timing to pre-v0.1.7c behaviour, hopefully reducing audio glitches for sd2snes Rev.G units
    • fixed corrupted file list display after playing an SPC file with a scrolled file name
  • Cosmetic changes:
    • “Loading” window is replaced by status bar notification to be less
    • disruptive with very short load times
    • configuration settings no longer have the wrong color when changed

  • do not silently fail to load/save cheat files when the sd2snes/cheats folder does not exist (create the folder instead)
  • Cx4 core now runs at exactly 20Mhz
  • fixes:
    • MSU1: avoid missed control register status changes on rapid rewrites (fixes FF3 Dancing Mad, Zelda FMV missing audio)
