Gaming / Buying a new PC
November 05, 2016, 01:47:55 PM
Hello walruses and walruses,
I'm here to ask for some advice. I'm in the last year of high school (French education system bullc) and I'll soon pass the exams for the "Bac", i.e. French equivalent for High School Diploma in the USA. Before I get to CPGE (also French thing, here you can either go to college or CPGE, the latter being the "premium" option for good students), I should get a brand new PC, and I need some tips for one that will suit my uses (is that even English ?). Anyway, here are my requirements :

  • 15-17 inches laptop
  • No Pentium/Atom/i3 bullc, I already know this will NOT be powerful enough.
  • Programming in Python on it (best joke ever)
  • Run Android emulators at full speed (Andy, Memu, Remix OS Player)
  • Do a lot of retro gaming on it, such as running DeSmuME at 5x internal resolution
  • Windows 10 (no, really)
  • Run Linux VMs on it without cing up the computer's speed
  • Enough RAM (8 GB is cool, 16 GB would be perfect)
  • I do not want to play PC video game things (Halo, Overwatch, i.e. things which play on XB1/PS4)
  • Run Dolphin 5 emulator at max settings and full speed. For who who don't know, that's a GC/Wii emulator. You may think I don't need a powerful PC for this, but... Just read this from their website:
    [spoiler]Which CPU should I use?

    Dolphin is a dual core application that relies upon IPC (Instructions Per Clock) for performance. Additional cores will not make Dolphin go any faster, though an "extra" core that Dolphin isn't using may help slightly by keeping background tasks from using the same cores as Dolphin.

        Intel: Newer Core i5 and i7 processors such as the i5-4670K and i5-3570K are extremely fast and very affordable considering their relative power. The K series allows for overclocking, which can further improve the performance of those CPUs. Core i7 variants yield almost no benefit in IPC over the i5s they are based on, so save the cash if you're building a Dolphin machine. For laptops, you can rely on the i7-4700MQ and i7-4930MX for the absolute best performance. Most games will run very well on any of those processors.
    Which GPU do I need?

    Compared to processors, choosing a GPU for Dolphin is a fairly simple task. The more powerful the graphics card, the more pixels and enhancements you can throw at it before you'll see slowdown. However, the biggest thing to watch for is making sure the GPU supports DirectX11.1 and OpenGL 4.4. Dolphin emulates a console that functions very differently from a traditional PC, and uses the latest D3D and OGL features to reduce overhead. If you do not have those extensions, performance will suffer.

        NVIDIA: Due to the importance of the OpenGL Extension "Buffer Storage" no NVIDIA GPU before the Geforce 4xx series can be recommended. Despite being a bit old, the Geforce GTX 460 will handle almost any game you throw at it in HD resolutions. Older NVIDIA GPUs will still be able to run the games fine, especially within the D3D backend and in OpenGL with older builds still using the "Vertex Streaming Hack."
    [/spoiler]
  • Not too expensive (I mean, the max price would be €1500, so currently $1671, £1334 or CAD∞ CAD 2240

That's it :P I hope you'll have good examples of laptops which would fit my conditions :D

Well, I basically get this thing :

(The connection with the TI-Nspire units is not available)

And of course, computer rebooted, software reinstalled, nothing happened...

I'm on Mac OS X 10.11.6, neither v4.3 nor 4.2 of TINTS/TINSS did work...

    Well, 1-2 weeks ago, a mysterious programmer registered on TI-Planet an gave us that :
Quote from: nBootDudeHi, I've got a present for you.
With this tool you can boot straight into linux, if you figure out how.
boot1 3.00.99 only, use the bundled nsNandMgr until a 'fixed' version is released.

After several hours of work from critor, Eurêka :
Quote from: critorGot it ! :D
Linux straight from the Boot1 ! :bj:



Donc apparemment, le Manuf avec nBoot dedans permet de lancer du code non signé à mettre dans la partition Diags.
Et donc d'alterner entre l'OS Nspire et Linux avec la combinaison de démarrage :nses: :nsme: :nsmo: .

Sympa, plus besoin de forcément démarrer l'OS Nspire et activer Ndless pour lancer Linux, ce qui dans le contexte d'une prochaine mise à jour de l'OS est une bonne chose. :)

(Yeah, G translate for those who aren't Canadian in here :P)

So, he releases a little news, saying all the new possibilities which would be allowed by this :P And he works... on the most incredible Nspire tool ever  O.O

Quote from: critorVoici donc ControlX, 1er gestionnaire de démarrage tiers compatible nBoot, te permettant le contrôle total de ta TI-Nspire CX HW<W ! :bj:


Le développement relativement rapide s'explique par le fait qu'il partage une grande partie de son code avec nsNandMgr/BtMg.

Fonctionnalités automatiques :
  • lance automatiquement un Boot2 compatible nBoot si trouvé dans l'une des partitions Boot2/Diags/ExtnD (4.0.3 de préférence, ou sinon 4.0.2)
  • patche le Boot2 à chaud pour activer automatiquement Ndless 3.1/3.6/3.9/4.0.3/4.2 si présent (code développé par Excale - seul le Boot2 4.0.3 est géré à date)
Bref, enfin le retour de Ndless reboot-proof ! :bj:

Fonctionnalités accessibles via menu (combinaison de démarrage :nsct: :nsx: ) :
[list=1]
  • amorçage normal du Boot2 via le Boot1
  • lancement d'une image de la partition Boot2
  • lancement d'une image de la partition Diags
  • lancement d'une image de la partition ExtnD
  • suppression de la limite empêchant l'installation d'un OS antérieur

  • activation de ControlX (le Boot1 amorce sur la partition Diags)
  • désactivation de ControlX (le Boot1 amorce sur la partition Boot2)
  • désinstallation de nBoot


ControlX permet donc de désinstaller nBoot, si jamais une future mise à jour de TI arrivait à bloquer les machines ainsi modifiées.
Les images lançables directement par ControlX (options 2/3/4) sont :
  • les images au format des Boot1.5/Boot2/Diags
  • les images au format Linux (voir l'exemple dans nBoot)
Ces images n'ont aucun besoin d'être signées, et on peut donc exécuter tout ce que l'on veut.
L'idéal si quelqu'un veut développer une image lançable par ControlX, est de partir du format d'une image de Diags, d'y coller son code et d'en corriger les champs de titre/version/taille dans l'entête.
Si l'image lancée est un Boot2 4.0.3, elle sera patchée à chaud avant exécution pour activer automatiquement Ndless.

ControlX gère jusqu'à 9 images par partition, là où nsNandMgr/BtMg en gèrent 11.

Voici ma partition Boot2 actuelle, telle que vue par ControlX :

J'ai juste, avec BtMg, échangé les Boot2 et Boot1.5 4.0.3, car cela permet un démarrage plus rapide de la machine.

Voici ma partition Diags :

On y retrouve donc ControlX et le logiciel de diagnostics.
Contrairement à la release initiale de nBoot, le logiciel de diagnostics reste donc utilisable et permettra dans certaines situations de débloquer la machine sans besoin d'un tournevis pour retirer la batterie ! :bj:

Voici ma partition ExtnD :

On y observe donc Linux, ainsi qu'une copie du Boot2 4.0.3.
Il est très important de garder une copie du Boot2 4.0.3 en partition Diags, car de prochaines mises à jour de l'OS écraseront la partition Boot2 avec une nouvelle version du Boot2, non gérée par le patch d'installation de Ndless.

En mode automatique, ControlX préfèrera toujours amorcer sur une image Boot2 gérée, si trouvée.

  • new 3rd party Boot1-level menu ( combo)
  • can run any image using the official Boot1.5/Boot2/Diags format found in the Boot2/Diags/ExtnD partitions
    (the images just have to be concatenated in the partitions but don't need to be signed - so you may run official Boot1.5/Boot2/Diags images, modified ones, or even your own boot tools)
  • can run any Linux image found in the Boot2/Diags/ExtnD partitions
    (see Linux image format in the initial nBoot zip)
  • can patch the minOS value in the BootD partition, enabling you to install older OSes
  • does automatically look for the best compatible Boot2 to boot (4.0.3) in Boot2/Diags/ExtnD partitions and automatically install Ndless (reboot-proof)
[/spoiler]
The dev is still ongoing, so stay tuned, but really critor almost killed me this time :crazy:

Well, critor, congratulations to you and the Ndless team, you've broken Ndless 4.2's record for jailbreaking rapidity !





WOW :p
