Emulação de Consoles no PC (2018)

afonso220 disse:

Muito bom, mais em cada tópico do emulador, você poderia ter colocado qual seria a configuração minima para o emulador rodar os jogos
sem travamentos etc, pois a maquina de teste que está usando é forte, então entende-se que quase todos vão rodar sem problemas, agora em pcs
mais ''básicos'' ou menos parrudo, não se sabe como ira ocorrer essa emulação.

Muito bom o tópico, gostei bastante!
Só não entendi qual o problema de selecionar widescreen no emulador do PS One, você comentou que não recomenda mas não informou o que de ruim acontece caso a opção seja selecionada.

-Uchiha- disse:

Removi do Guia a parte do "Não recomendo" por ser uma opinião pessoal. Eu particularmente não recomendo pois em jogos 2D, o aspect ratio fica deformado... irei dar uma revisada no tutorial do PSOne acrescentando novas informações...

Julaes disse:

A imagem "estica" quando a opção é selecionada?

Muito bom o Demul Uchiha. Não conhecia.

-Uchiha- disse:

Entendo o questionamento, mas é mais complicado que isso... vou ver o que consigo fazer mais o problema é que os requisitos mínimos variam muito de jogo para jogo. Alguns jogos são mais exigentes que outros, além de em determinados casos, o emulador ser melhor otimizado para X jogo.

De todo modo, vou tentar elaborar uma metodologia para atender isso.
