V zasade si mozes urobit pre svoju hru urobit custom FPGA konfiguraciu .. napr. 320x256 rozlisenie v 64 farbach s 128 16x16 sprajtami a so SID zvukom .. nie je vsak vela borcov co to vo VHDL/Verilogu nakoduju .. ale cas ukaze.

Tak ten hw je nějak univerzálně napsaný. Neni možný psat spešl soft pro fpga. To by byl bordel... to rovnou Lemmings napsat pro fpga a hotovo ne? Ale to je hoooodně vzdálený myšlence Nextu. I tak je Next daleko od ZX.

Peter Ped Helcmanovsky: "BTW, I tried to check the github to see how the whole architecture is done, but I was unable even to find these sprite parts, etc... so I think it's heavy work in progress with some parts being not public yet, or I'm very bad at searching."

- Peter je vyborny koder a pyta sa kodera Lemmingov, kde sa da vlastne ku nativnemu infu o SpecNexte dostat .. toz tak, enigma. V. Trucco ten brazilsky paznecht, ktory ma kodovanie FPGA pod palcom mlci uz niekolko mesiacov, informacie idu interne iba pre par vyvolenych.

Osobne nejaku custom konfiguracie cakam, podobne ako Ts-conf pre ZX-Evo a uz som nasiel zopar tipkov, co hovoria, ze napr. urobia nejaku gamesu pre SpecNext ale zvuk napriklad neporiesia cez AY chip /su tam rovno tri, teda AY 9 kanal/ ale napr. iba cez jeden SID na muziku + jedno AY na pif paf sfx. SpecNext ma nativne este 4 x 8 bit DAC, trochu ala Amiga.

Existuje elektricke schema desky? UCF soubor jsem nasel ale schema jako kdyz by snad nebylo.

Ani ja som viac nenasiel, myslim, ze aj na FB a ofiko fore sa o to niekto ziadal ale .. nedoziadal sa.

Ta krabice se pomalu stává tím jediným, co mě na tomto projektu zajímá... ale info o ní taky není žádné . Naposledy tu na téma krabice Joe dne 21.4. psal:

A za 2 dny zemřel Rick Dickinson.

Je mi jasné, že to Joe takhle nemyslel, a hlavně doufám, že to takhle nemysleli ti, co "slibovali info"...
Rickova odchodu je mi velmi líto , nicméně pokud jde o jeho práci na krabici, předpokládám, že byla hotová, takže se to tím nijak nezdrží... či ano?

- male mini info o pracach na plastovej krabici SpecNextu, vylisky, formy, matrice a spol. Na krabici okrem Ricka makalo viac ludi, jeho kamosov z branze, este jedno vyznamne meno /zabudol som, da sa vyhladat .. asi Phil Candy/, ktore sa v podobnych veciach vyzna a ten to cele ma osefovat do uspesneho konca, tym nemyslim dalsieho umrtia, heh.

Díky, to je asi první konkrétnější info, co jsem na toto téma viděl.
Ale abychom z toho neměli až takovou radost, tak se ty obrázky nedají zvětšit ... U toho nákresu by se to velmi hodilo...

Vsetky tie obrazky tam maju take prtave, uz im parkrat povedali, nech mame moznost si to stiahnut "full HD", ale je to furt po starom.

bonus - ukazka SpecNExt basicu, je tam more novych features + sa snazi to spolupracovat s HW sprajtami, Layer 2 /akoze nova ULA/ a podobne, na vyblbnutie dobre .. zjavne.

pretoze brazilec nedokaze napisat 2 vety ako je mesiac dlhy, tak sa akurat spekuluje a hada .. az ho to dozralo a nieco malo napisal ku teme SID zvukovka v SpecNexte.


Victor Trucco: "Please stop spreading rumors. I, Victor Trucco, removed the SID to make some room for other features and to make a "better" use of the space in the FPGA. Nothing to do with Paul, IP, or whatever, just my decision. Actually the SID still there at the sources, as the FM module (YM2413), I'm just building the core without these modules included."

Victor Trucco: "To my surprise I did some tests including the SID in the last compilations and still fits, but it stays in the limit of fpga. Then it might be that including it means having no room for future development and not even for bitstream patches."

Victor Trucco: "Anyway, the build with SID included can be used as a secondary core, since the multiple cores boot was tested and it worked great. Long story short: wait for the launch release (the one with the cased Next), I have not decided anything yet at this moment."


- v preklade teda nic nebrani tomu urobit pre SpecNext soft co bude vyuzivat napr. kombo SID+AY, teda custom FPGA konfiguraciu.

Myslím, že se z toho projektu začíná stávat správnej punk - alternativní konfigurace FPGA existující ještě před vydáním finální verze stroje...

A to som dnes citam, ze Mike Dailly /DMA design, Lemmings/ skemra aby do volneho miesta na FPGA nakodovali kvalitny blitter .. mimochodom .. copper procak v SpecNexte je tiez majkiho "dielo".

- chlapik co stavia pre SpecNext velku hru triedy stare pecky pre Amigu alebo Megadrive. Styl Chaos Engine, snazi sa o Terminator temu, kvantum kodu, pixel art grafiky, audia. Co pozeram je naozaj sikovny, odhodlany, vela rokov skusenosti v odbore a vyvojarske nastroje si robi sam.

- to video co som tu uz daval je jeho praca, asi to mysli vazne, heh.

cerstve info ..

Jens Axel Søgaard: "On Mist and Mister it is trivial to change the fpga core. Presumably this is also the case on the the Next?"

Allen Albright: "Yes it's easy to change the core. People with boards are getting good at it since that's what happens when there is a distro update."

Victor Trucco: "Actually there are an easier method Allen Albright. If you have another core in the flash, you can just write to Next Reg 16 (0x10) to reboot to a certain core. Today the Anti Brick core goes at "position 0" on flash and the current Next core at "position 1". At cold boot the AB checks for the button pressing and reboots to Next core."

Victor Trucco: "So, you can have other cores at positions 1... 2... 3... and reboot to that versions with just the Next Reg 16. you can have even other systems. I build the Belavenuto's Colecovision FPGA for the Next pcb a while ago and used for these tests."


Pojde teda o celkom trivialnu vec .. nic vam nebrani mat Speccy s AY, SID, Pokey zvukom, eh.

Hmm a nebylo by lepší mít prvně plně funkční a kompaktibilní zx spectrum, a 128k ? A pak vymejšlet další ? Zatím vyjde líp skoro jakejkoliv simulátor v PC...

- bezny uzivatel ziadne problemy nevidi.

- skusenejsi uzivatel vid komentare /tags: VGA, HDMI/.

Robin Verhagen: "You can also run VGA timings and use a SCART to HDMI converter fed by a custom RGB cable that plugs into the VGA port. No functionality is lost on HDMI, you just have to work a little harder to achieve it. I'm running my NIRVANA games on VGA timing 1 here, they display perfectly."

Henrique Olifiers: "Just to complement, it's is possible to have perfect timming with HDMI. The early firmware versions were like this. The problem is that it caused incompatibility with some HDMI TVs (and the odd monitor too), so the timmings were adjusted. We can certainly have two branches of firmware for those who have HDMI monitors capable of working with the right timmings of the original Speccy (like mine or Victor's monitors, for instance)."

A dev tim sa toho casu zameriava hlavne na NEXT aspekt tohto spektra, teda nove features .. V.Trucco vsak uz povedal, ze dodatocne ladenie stroja bude.
